What is gouache?

Gouache is a kind of pigment for painting, which requires a moderate harmony between water and pigment to paint, but it is not completely dependent on water like watercolor.

What are the foundations of gouache painting?

Gouache painting technique is difficult. Many students have practiced for a long time, but the progress is slow and the effect is not great. This is mainly due to the lack of theoretical understanding of gouache painting techniques. The main way for students to understand gouache techniques is through textbooks and books on basic gouache techniques. If it conforms to the students' reality, a book that can be read, analyzed and studied, copied, experienced and expounded to enable students to master gouache techniques is a good book for students. Teachers can use it to illustrate the technical essentials intuitively, and students can also use it to illustrate the essentials intuitively and vividly, which is concrete and feasible to guide painting practice. However, at present, most books on basic art techniques are written by experts, which are only instructive to students. The specific painting method is generally simple or abstruse, and the painting method and steps are simple. It rarely talks about the key problems that plague beginners, such as water use, color matching and modeling. A large number of books use technical terms, so it is difficult for high school students to understand and accept them. In some books, the drawing methods and steps are rather general and difficult to understand, and the methods are simple. The model drawings provided are too mature and even misleading, so it is still difficult for candidates to copy, let alone guide their study.

The key of gouache technique lies in water use, color matching, pen use, modeling and adjustment.

I. Water Law

After students have a little understanding of the basic theory and skills of gouache painting, they can start painting gouache. One of the keys to gouache painting is to use water. Proper use of water can effectively shape the body and express the color. Water is not successful, painting is not successful. Gouache painting is a kind of painting in which powdered pigments are mixed with water. Pigment contains colloid, which will have different effects after dilution with water. Generally speaking, when painting gouache still life, we should use as little water as possible and cherish water as gold. Water and color should be coordinated, with more colors and more water, less colors and less water.

The nib is mainly colored and dipped in water. When one color is used up, the nib should be washed with water, squeezed dry with absorbent cloth, recolored, and then dipped in water to avoid touching the next color. It is very important for beginners to form this habit.

Light, thin and transparent objects need a little more water. Without water, they are easy to accumulate dust and dirt, so they are fresh when painted. When the water dries, they are pan-colored, light, gray and dull. Less water and multi-color are easy to dry, dry and astringent, showing no texture and luster, which is not conducive to color convergence. The bright part is slightly thinner, so it is faster to use a pen. Use white paper background, the color is used successfully once, and the color is beautiful and clean. The dark part needs less water, more colors and more effects.

Second, the color modulation method

Tone matching is the key to rich gouache color. Improper color matching will lead to raw, gray, dirty, messy, fire and vegetables (pseudo color). Generally speaking, after mastering the skills of using water, when painting, analyze the color of any object into color levels and show them step by step. The main object and the bright part of the object should be painted thicker, and the secondary object and background should be painted thinner.

In order to make pictures and objects have rich colors, the skill of color matching is to spread pigments on the palette and add other colors one by one around the inherent colors of objects to form a series of colors that are both related and different, showing a rich color system.

Specific method: 1. Give priority to the main color and color of the picture, and choose any inherent color, such as red, yellow and green, as the preferred color. 2. Draw any object, select the inherent color, spread the pigment of this color on the palette and add it around it one by one to bring up a series of hues. Such as apples-choose yellow to draw the semi-bright part, add a little white powder to the bright part on the basis of yellow and dark color, and appropriately blank the highlights first. Draw the dividing line between light and dark with a small amount of purple, so that the yellow apples are light yellow, yellow, medium yellow, green yellow, dark yellow and other series from bright to dark. In this way, there are both connections and differences between colors, and if used properly, they can show a rich sense of color and volume. Pay attention to the expression of apple's three-sided pentatonic. 3. The thickness of the pen color should be treated differently. Generally, it is advisable to cover with white paper, and the bright and semi-bright parts are slightly thinner. Use white paper as the backing to make the color bright; The dividing line between light and shade and the dark part should be painted thicker; The hue of bright and semi-bright parts is not allowed to be dry, and it can be painted thicker. 4. In the color series, colors should be added, not too many kinds (easy to get dirty), avoiding the same amount (easy to get gray) and repeatedly stirring colors (not fresh). Add black and white bit by bit, not too much at once (easy to get dirty). 5. If the hue is not clear or the color is too different from the adjacent strokes, it is dirty. You should wash your pen and readjust it. A good painting should be stain-free. Any color has a different hue. The dirty color makes the painting look gloomy, dull and dull.

Third, using brushwork

Gouache belongs to a special kind of watercolor, namely opaque watercolor pigment. Because it is cheap, easy to learn and easy to use, it is often used as an introductory painting material for beginners to learn color painting.

What's the point of gouache?

When I was a freshman, there was a popular saying: "The shape is not important, but the surface (of course, I don't really ignore the shape)." The attractive viewpoint of gouache painting is not the shape at first, but various blocks expressed by brush strokes. There are also rich colors, and each piece of a red apple has a different color ~ ~ ~

What is gouache? Compared with oil painting and watercolor painting, gouache is a kind of painting between oil painting and watercolor painting. It has some excellent qualities of oil painting and watercolor painting, but it is not as good as them in many aspects. Compared with oil painting, it is not as thick and rich in color as oil painting. Compared with watercolor, it is not so transparent, and there is little ink drop feeling of watercolor. However, gouache is bright, saturated and bright in color, has a certain sense of breathability, and is free to take off the wine with a pen. This should be the characteristic of gouache, which is irreplaceable by oil painting and watercolor. When it dries, the color will fade.

Coloring it requires long-term gouache sketch practice and constant experience accumulation. Gouache painting should also have a degree, not too much. The ratio of water to gouache pigment also varies from person to person. Personal habits are different, so we must explore saturated pigments.

It is not enough to paint gouache as a high-grade art work, but only to reflect the characteristics of gouache in the painting. The author also needs to have certain cultural and artistic literacy. I've been painting gouache for a long time, but sometimes I can't do it, because sometimes my level can't reach my own idea. My eyes are high and my eyes are low. Gouache painting is easier for beginners to master and modify, laying the foundation for other color painting methods in the future.

Learning gouache is nothing more than a kind of color training, cultivating one's sense of color and improving one's appreciation level.

Introduction to gouache painting

Gouache painting is a kind of painting made by mixing powder pigment with water. Its performance characteristics are between opaque and translucent, and colors can produce gorgeous, soft, bright and rich artistic effects on the screen. Powder content will limit the smooth activity of watercolor. The color saturation of gouache is very high when it is wet, but it loses its luster after drying, and the saturation is greatly reduced, which is the limit of its color purity. Studying gouache can have a good understanding of color and a new understanding of color transparency. In the process of learning gouache, you can learn how to mix colors and further understand the importance of color to gouache.

What is the evaluation standard of a good gouache painting?

The standards of good gouache painting are: beautiful composition, uniform tone, clear contrast between color and hue, accurate contrast between cold and warm, harmonious relationship between pure gray and color, distinct layers of objects in the picture, distinct layers of individual objects, proper treatment of light source color, inherent color and environmental color, and strong sketch relationship. With the above items, it meets the standard of good gouache painting.

The difference between gouache and watercolor painting

First, the pigment materials are different.

Gouache pigment is a powdery material, which is fixed with glue and has strong coverage. So when you draw gouache, you often start with the darkest color. It can be covered layer by layer. If you are patient, you can get the same effect as oil painting, except that the color of the pigment is darker when it is wet and lighter when it is dry. There are roses, violets and other purples that are easy to turn out and do not need to be primed. Gouache color particles are very washable. When dissolved in water, the color is beautiful, but it can't cover the background color. The colors of ultramarine, ochre and earth red in watercolor pigments belong to mineral pigments, which are easy to precipitate when used alone or mixed with other colors. Most watercolor pigments are transparent. Watercolor can enhance the transparency of products, especially in the texture of transparent objects such as glass, metal and reflective surfaces. Transparent and reflective surface is very suitable for watercolor expression. When coloring, go from shallow to deep, try to avoid heavy pen, and do it in one go.

Second, the painting methods and materials are different.

Watercolor pays attention to dry and wet painting, with too much water, very light colors, less coverage and heavy gouache painting. When painting, gouache is covered, dry and layered. Gouache painting, as an independent art form, can be divided into three categories: still life, scenery and figures. Although gouache has the advantages of rich content and clear and stable color, it is quite difficult to learn and express because of its diverse characteristics in the process of drying and wetting.

Gouache painting takes water as the medium, just like watercolor painting.

Therefore, gouache painting can also draw the same hearty effect as watercolor painting. But not as transparent as watercolor painting. It has something in common with oil painting, that is, it also has certain covering ability. Oil painting is different from oil painting. Oil painting is based on oil, and the dry and wet colors have hardly changed. But gouache painting is not, because gouache painting appears in the form of water and powder, and the wet and dry changes greatly. So its expressive force is between oil painting and watercolor painting. Watercolor painting is characterized by transparent colors, and objects are represented by the superposition of dark and light colors. But gouache is opaque and translucent. If it is covered or superimposed on the colored base layer, then this process is actually an addition, and the color of the bottom layer will affect the color of the surface layer to a certain extent, which is why it is difficult to master.

Gouache is an independent painting between watercolor painting and oil painting. As far as painting materials are concerned, the use of water-mixed glue and powdery pigments in painting is probably the earliest expression method used by human beings in painting, which can be confirmed in Dunhuang murals in China and tomb murals in ancient Egypt. However, gouache is a very young painting. Although it is also painted with rubber powder mixed with water, it has no direct inheritance and development relationship with painting with rubber powder mixed with water in ancient times. In fact, it has many similarities with watercolor painting and oil painting in artistic concept, expression form and painting system, because it is a kind of painting evolved from watercolor painting itself.

The fundamental difference between gouache and watercolor painting is that the pigment of gouache is an opaque pigment with strong hiding power. Although gouache and watercolor painting are basically the same in artistic concept, watercolor painting uses transparent pigments, which makes them have obvious differences in painting steps, expression techniques, painting interests and picture effects. However, the hiding power of gouache and the thickness of pigment in the painting make its expression similar to that of oil painting. Although the performance of the mixture and pigment used by them is different, they have their own characteristics in expression techniques and artistic pursuits, but it is for the above reasons that gouache not only becomes a form of expression of color art, but also becomes an important color training course in the basic teaching of art colleges because of its unique and compatible characteristics. Gouache is usually regarded as one of the basic contents of the entrance examination for art colleges, which objectively promotes the popularization of gouache.

What is gouache painted with?

I need a set of gouache chalk from Beijing Xiedetang. An iron box is a paint box for gouache paint. The sponge covers the paint squeezed in the paint box. Then spray some water on the sponge and cover the paint box to ensure that the paint will not dry and moisturize. Usually I use the lid of the paint box to mix colors and buy a paint box. It's best to buy white ones, which are not easy to have color errors.
