Gouache nature and techniques, is closely related with the oil painting and watercolor. It is a kind of painting which is between oil painting and watercolor. It uses water-soluble pigment like watercolor. As with gouache opaque to the deployment of more water, will produce different degrees of watercolor effect, but in the activity of color and transparency, and cannot be compared to watercolor. The general effect of reflective gouache show and Transparent Watercolor bright effect is not the same, so the method of gouache is generally not used water color, the color white color brightness adjustment, to show their unique color effect with thick paint. This is similar to the drawing method of oil painting. Because opaque gouache and oil paints are hiding pigments, so gouache is between watercolor painting and oil painting of a painting, it is through some methods and skills to learn watercolor painting and painting and develop their own skills system.
If there is a color on the basis of overlay or overlay, then this process is actually an addition, the underlying color will affect the color of the surface, which is where it is difficult to grasp. However, experienced painter often is to use this feature to express its gouache color itself and unique artistic charm.
Sketch when the deployment of color, is based on the correct observation and understanding of the relationship between the object color. Deployment of color can not be isolated to see a piece of a tune, draw a piece. To consider the whole tone and color relations, from the whole to determine each color. Gouache painting color is not easy to converge, should also be based on the clear relationship in the color, the color of the color to be several tries, ready to draw. Avoid from the whole, see a piece, tune a piece, draw a piece, then adjust a piece of change. Gouache color when wet dry deep, shallow, wet change obviously.
If you use the powder color (white), or have painted a thick layer, and then color painting, but also the use of absorbent paper, wet change pigment is more remarkable. The gouache color is not easy to make a correct estimate. Difficulties in color cohesion, coverage and modification. This is an obvious characteristic and difficulty of watercolor painting. Beginners should pay special attention to this problem. So start painting heavy colors first. In general, while the screen is wet, color wet and wet than, one breath finish, color relationship easy to master. If in the case of the color has been dry again, covering color, it should pay attention to color dry and wet change.
Use of water
The use of water in gouache watercolor painting though not so important, but also can not be ignored. Water is mainly played by dilution, the role of media. Color, color pen and thin change, and water use, there is a close relationship between. In general, properly can make the picture smooth, moist, and the effect of water. Too much water will reduce the chroma, caused by water stains, stains and water deposition. The shortage of water will make the color of dry, thick, hard pen. Usually use fluent pen, cover background, as appropriate. In the dark, empty and draw distance, can be appropriate to use more water to enhance its transparency and virtual distance. From the painting step. In the shop to tune when the water used more, the layer is thin, easy to coloring. In the painting process, the water is too dirty to change in time. Especially the painting brightly colored parts, toning water should be clean.
Due to various types of pen can be used as gouache, so waterpainting pen tip is unusually rich. And is drawing oil painting. The process of painting and watercolor brushwork, continue to develop. Gouache common style.
"Brushwork" -- subtle handwriting. Flat screen color;
"Division" handwriting appeared, but its thickness did not change significantly;
"Thick layer division" -- intricate overlap, color, thickness and thickness;
"Stippling method" -- the use of color space, began to feel the mixing principle, with dense small brush (color) image. (this technique used less, difficult to grasp, when it is premature to follow)
Oil painting techniques
In addition, gouache also absorbed the painting oil painting techniques. Oil painting knife can be painted, can also use homemade bamboo knife painting. Gouache in the absorption of other kinds of painting technique of pen, gouache, must from the characteristics of the performance of the purpose is to enrich the gouache painting techniques to enhance the expressive force of gouache. In general, the painting of virtual office and shadows, shadows, strokes, and some vague flat color thin, to increase the false sense of distance. In the foreground, implement and light painting, brush to reveal some color to be thicker, to enhance its strong, prominent and clear effect. Of course, these are needed from the processing of the whole picture point of view, the use of different strokes. Strokes also have a holistic problem. A painting pen must change and unify, form a sense of rhythm. To prevent the lack of overall intention of the messy pen.
Gouache color due to dry faster, dry and wet changes significantly, and the water will flow into the picture, color, and prone to water seepage, so master cohesion skills, for drawing gouache relations. Convergence of watercolor painting can be divided into wet and dry ground and then pressed the three methods.
The so-called wet joint, are adjacent blocks before taking advantage of a color is not dry up second, three pieces of color. Or two adjacent colors touching. Or a color in the wet point into other colors, let the infiltration. Or in different parts of the head were dipped in several different colors, water use pen to paper on the belly, let the natural.
The so-called dry joint, it is adjacent to the block in front of a color is dry, then second, three pieces of color.
The so-called crimping is adjacent patches (body turning or different physical objects), before a color painting was slightly larger than its shape, second, three colors into a rhythm. To prevent the lack of overall intention of the messy pen. Next, pressure is placed in front of a color, the color should be out of shape before a piece of. When pressed, pay attention to the colour (crimping up color) cover color and adhesion, the color generally pressed than painting color slightly thicker.
The so-called coverage, is to draw one or several layers of color in the painting layer. The main function of coverage can be summarized as two points: one is to make the picture color overlap, thickness change, is a technique of image building; two is a modification method. Cover color gouache color is relatively strong, but each has difference, called water plus paint, covering the bad master is easy to make the background (covered layer) on water stains caused by dirty color. Sometimes it's very thin.
Solid color, is the object itself presents the inherent color. To grasp the color, the main object is to grasp the exact hue.
Because solid color occupies the largest area in an object, it is very important to study it. Generally speaking, solid colored objects showing the most obvious place is the middle part between the surface and the back surface, which is a note of gray sketch, we called half tone or color. Because in this range, the object is less affected by external conditions of color, its change is mainly the changes of lightness and hue change itself, it is often the highest saturation.
(1) draft starts like the sketch, in pencil first set position and proportion, need not use rubber, so as not to damage the surface, affect the coloring effect. Then use the color according to the finalized, still life with brown or ochre tone, ultramarine blue can be finalized. Color line can be slightly heavier, and can be finalized
Thin color slightly light and shade, pave the way for the next step coloring. Some other ability, also can be directly used color line drafting, not shown light, direct coloring.
(2) after the shop tone finalized, quick review the overall tone and color, be sure, as soon as possible thin coating. Now don't take shape and strokes, according to the fresh color impression caused by bold sway, the picture color environment. Some people after finishing the last color, eager to specific characterization. Should further adjust the color, make the relationship between color and the color, is consistent with the real feeling.
(3) the concrete mold is on the basis of the correct comparison of the big relations, further carries on the concrete mold, starts from the picture main body, completes one by one. Focus on painting an object dry and wet change easy to master, but also easy to shape its light and backlight different color changes. The eyes always sweep around the ring, starting from the local but not local care for this and lose that. To see the object and background and the relationship between the spring, he objects to grasp the sense of proportion, the details can be left scratching step. The use of color to color it properly thickened, right part of color can be retained, increase the screen color level.
(4) the details of characterization to extra trivial details are omitted, but important details of image texture features and performance should strengthen the ruling, touch. Details should be integrated into the whole. The last stroke is the most important, it will not be covered and revealed to the appreciation.
(5) adjustment, complete the studio outside a sketch, as a basic practice in general to eight hours, to a profound and accurate. Skilled after three or four hours can also be more fully behaved. Painting time is longer, easy to fatigue eyes, color sense easily weakened, the specific characterization and easy to forget the whole. When painting is nearing completion, restore a first impression, check whether the picture: some places destroyed in depth characterization, and the details of the local color is not "jump out" picture, there is no other. After the inspection, adjustment, modification, processing. Wrong place, picturesque too thick, to wash and draw, until completed. Gouache dry and wet techniques should be controlled to what extent? What are the scope of application? Using the techniques of dry and wet gouache, mainly refers to the amount of water and white color.
Have a strong ability to cover the gouache color, but not without regard to any graffiti, it has its own certain coloring methods and steps.
1, from the local to the whole gouache is a color painting, with watercolor painting, painting is starting from the dark color block. The overall focus and starting from the general principle of our painting, color and large color, play a decisive role on the color screen, color should first draw the main color picture of the quasi composition, then the local shape and detail description.
2, from the deep color to bright bright color is thick, thin Tuliang up again. Draw a deep color, bright color easy to be covered; on the contrary, is generally the first to draw a large area deep color (including the dark and bright and heavy color), the color of the screen frame to be determined. Gradually to intermediate color and bright color. With a bright color screen, or to put bright color, the color is slightly thinner, local small area deep color. If the intermediate color, paint besmear first intermediate color, use juxtaposition method, respectively to the small area of dark bright color paintings in the past. Method is not dead, according to the situation flexible grasp.
3, from thin to thick painting thin paint dilute with water paint, like watercolor painting, according to the overall color feeling, quickly thin coated again, resulting in the overall picture color environment, and then gradually thickening, in-depth performance. Thin coated the right place to be good at keeping, so that the screen color is thick and thin, in order to increase the color level and heavy effect. Not like painting, gouache and acrylic paint adhesion, can be painted thick. Gouache painted thick to thick appropriate, too thick easy cracking, so thick and no color wash painting.
(1) dry drawing and wet drawing in gouache, dry brushwork generally refers to the method of overlapping thick coating. This method can be repeated again not to draw, draw again, performance object is sufficient and profound, and is also suitable for beginners to master. The thickness of painting, oil painting has a similar effect, deep feeling. Wet drawing is a thin painting, play the color seepage effect, coloring times should not be, even the white part can free white paper, watercolor has moist flow charm. Of course, some local thickening is also possible, dry and wet combination will enhance performance.
(2) set and reset
Juxtaposition is placed in parallel strokes paper, coloring number of times less, began to use the color that is thick. Such as the emphasis on two degrees of space screen. First with the hair color line hook about rough outline and structure, add color with the color juxtaposition set up, press the color line.
Reset is a method of laminated color, color to color overlap point, color, line color. The painting is mostly used to reset and juxtaposition, and fully express the object.
(3) the master color changes of wet and dry wet change is one of the characteristics of the gouache. The color coated paper, wet feeling when appropriate, that will become pale grey some dry. Do not understand this feature often brings passive coloring. Master this characteristic, anticipate the effect after dry, can avoid after adding color becomes uncoordinated "patch"". Painting, should be thin to thick coloring. First thick painting and then thin coated dry and wet change; first thin painting, gradually reduce water painting thick, dry and wet change is not obvious, easier to master. Modify the screen is also suitable for thick coating. Can also be modified to be painted around a little water, modified part will naturally unify after dry.
(4) the color of the connection screen needs to be linked to the natural color of two blocks, from bright to dark to transition mellow, color to connect properly. There are three methods: 1, using the wet paint, the bright colors and dark, the color and other color, because of the role of water infiltration interaction, so the effect will be natural and smooth. Again not according to this method, can draw again at.2, and between the middle brightness color painted, although there are obvious pen marks, far see a natural transition. 3, two link stiff about, which can merge in the adjacent dry brush a few levels, increasing the transition. Also using a pen dipped in a small amount of water in the light and stiff about a few times, and make joint and transition layers from the brightness or color, which is naturally turning.
(5) use Bibi color on the paper movement, the emergence of pen marks, that is, strokes. The general picture of the painter painting strokes can be seen roughly the order and how to use the pen to the shape of the object, the pen is not the purpose, is a means of expression, many painters style is different, some large aspect, some small amount of plotting. What a good way? How to use? Should focus on the performance of the object from the objective, according to the different feelings of different images of different structure, texture and author, based on the performance. Starting from the performance of the object, for the performance of body structure and color, flexible use of coating, pendulum, point, hook, heap, sweep strokes are described.
Dry drawing: that is much less water powder, this technique uses the pen squeezed moisture, color is no water or less water, so that the pigment into a
A paste, deep to shallow, from the surface to the details, repeat coverage and in-depth, draw more and more fully, and with the progress from deep to shallow, continuously transferred more white to light screen. Dry drawing pen and a comparison of Sezhi, dry shape, but more specific and strong, easy performance certainly and clear form and color, such as object is concave and convex, light painting subject matter and wonderful details. This technique attaches great importance to the observation accuracy, pen strokes, sure, every on behalf of certain form and color relations. Dry painting also has its shortcomings, the screen too much use of this method, coupled with improper use of technology, will cause the picture dry and dull. But the dry color of dry painting change small, for exercise color effect is bigger, also easy to master.
Wet painting: this method and dry painting on the contrary, more water, less powder. It absorbed the watercolor painting and ink painting techniques, but also can play the most gouache using "water" benefits, use water to dilute the pigment rendered. Wet painting can also use paper and color transparency to obtain as bright and refreshing as watercolor. But the wet technique the watercolor is more demanding, because the gouache coarse, requires the wet paint to see the picture, the wet paint part of a successful rendering, excessive smearing or multiple times will inevitably lead to ash and greasy smear picture. However, the pen is smooth and flexible, the effect is moist and soft, especially suitable for drawing loose objects and virtual background and dim surface of objects. Such as play properly, it can show a vivid charm and with great eloquence all blend into one harmonious whole. Its color with the flow of water and mutual penetration, and sometimes unexpected results. To make such a wet effect
The fruit, not only pigment to be diluted with water, the paper also according to local and global needs in order to ensure the water wet, wet time and convergence of natural color. Control of the wet and the actual operation, the drawing step speaks a lot, no longer do not dwell on one by one.
Characteristics of wet and dry painting
The characteristics of dry wet painting gouache and application scope, basically as mentioned before. In particular: dry and wet drawing boundary painting is how to brush the water content to decide, generally believed that using powder and color more, painted thick, dry brushwork is, this is not accurate, because must be multi, multi colored powder, less water to become dry brushwork. Some people think that powder less, painting thin is wet painting, which is not accurate, only diluted pigment water can become a wet painting. Therefore, it can be said that there are many dry powder painting, there are less dry powder painting. On the contrary, the wet painting also has a powder multi wet painting and powder less wet painting. But whether dry or wet it still is better to use the powder characteristics properly, so that you don't lose gouache. Dry painting and wet painting, the two should be crossed when painting, just according to the actual needs of the picture, some wet painting use more, some dry painting use more. If a painting too much water, all wet painting to deal with the picture, it is easy to cause uncontrolled, loose objects, and lose color luster. Also, all of the dry brushwork, rely on the accumulation of color and white thicken picture will appear rigid, chapped and color loss, the picture is difficult long-term preservation.
Steps of wet and dry painting
In short, dry, wet painting only according to the painting steps, from wet to dry, from thin to thick order reasonable transportation, in order to play the best effect of dry and wet techniques. This is the general principles of the painting process to comply with the true use of the practice in accordance with the requirements of the picture flexible grasp.
Watercolor painting techniques
The first step: this flat pendulum floating composition gives the feeling is very natural, but also a form of composition. From the end of monochrome. With color should pay attention to, modeling to accurate.
The second step: This is a purple screen, purple is not easy to repeat painting. The first color to strive for painting accurately, so that the next step can have a good foundation. Yellow and purple is a strong contrast color, through the glass plate to two kinds of grey purple; strong color connected, the powder on the pear and orange purple crinoline dark color painted orange, partial warm contrast, a reflection color, porcelain and porcelain ability is strong, with purple in the warm color backlight components, so that the overall color change in uniform color bright atmosphere, very loud.
The third step: using dry painting performance shaping peach texture. With a small yellow green tone, draw the subtle changes in peach; such as the gap between the backlight, reflection, reflection, peach. The purple color of the lining cloth of pineapple very saturated, proper water. Such as yellow and white to yellow to orange and green transition, convergence, when the color of wet brushwork subtle, showing luster texture and flavor of pear. Vase by the light part of the pattern can be painted more virtual, partial blue purple flavor. The turning point painting some real, backlit with green flavor. This step should pay attention to the actual picture, strength, changes in temperature.
The fourth step: this step is closing, requirements and fine, must observe the whole. Affect the overall relationship where you do not hesitate to get rid of the vases, backlight adjustment, adjustable eplant and cooked brown painted pattern changes in the edge backlight, adjustable brightness and purple, behind the lining to close to the edge line with backlight, the sense of space is much better than the original. The relationship between some peaches, can bring warm heavy gap down. The edge of the glass carefully draw the string with a small pen, the texture, powder on the inside lining in some places with some cold grey. The pears in the white bowl also took a few pens. Before and after the formation of color perspective changes and the overall picture coordination. To make the picture more complete.
The fifth step: adjust the picture, details of the place, the general picture to deal with, messy things to remove.
The limitations of the color purity and brightness
Is realized by light color dilution, plus powder or powder containing pigments more gouache brightness increase. Dry and wet changes it is very large, often some color only add a little powder in wet and dry, its brightness shows or deep or shallow differences. Because the color of gouache dry becomes shallow, so make good use of gouache powder is the most technically difficult to solve the problem. With powder is gouache color charm, it makes the picture color full of gouache unique "powder" quality, and the middle is particularly abundant in color.
Personality differences of pigments
Gouache color is much more stable, such as yellow soil, red, ochre and orange yellow, yellow, yellow, olive green, pink and green, blue, ultramarine, cobalt blue and so on.
However, gouache in dark red, rose red, violet, violet color is very unstable, prone to turn color, not easy to cover. Transparent color less gouache color, only lemon yellow, rose red, violet and other few colors to draw gouache must fully grasp the gouache pigment color by understanding its personality, abilities, ability to cover the size, color of the high and low price. All these problems should be through practice, do Practice makes perfect.
A brush is characterized with high moisture, add color more, a color paint has the advantages of large area, due to the shortcomings of the water content is too large to draw strokes easily turbid, is not suitable for details. Langhao is characterized by less moisture, better than elastic brush, suitable for the characterization of local details. Along with the development of modern industrial progress, a large number of popular nylon brush on the market, in the choice of nylon brush, should pay special attention to its texture, soft and elastic, avoid an excellent. Excellent writing pen is often difficult to take the paint and drag the color easily on the screen, the coverage is greatly reduced. In the choice of the shape of a pen, choose different kinds of some, such as flat head, pointed, pettifoggery, for different occasions, different themes of painting.
Pigment is best to use authentic art supplies manufacturers tin tube production of professional products, it cream delicate, more saturated color. Don't be fooled by cheap inferior products. In the choice of paper, should use a high quality watercolor paper texture painting, water can not be too strong. Some poor quality paper, not only the water absorption also color, the color of dry black paint with this paper, the color of the screen is bright.
