A crayon is a pen made of pigment mixed with wax, painted with ten different colors. Crayons are not permeable and are fixed on the screen by force of adhesion. They are not suitable for using glossy paper or boards, nor can they be compounded by repeated stacking of colors. It is an ideal tool for children to learn color painting, and some artists use it for sketching and color recording. Crayons can be produced by casting and extrusion methods. The wax is usually made from 40% C16 to C18 fatty acids, 40% waxes, 5% pigments and 15% crayons.

Of course, like a lot of similar methods, and then combined with the usual painting, specifically introduced some of our research in the sum up and explore the methods:
1 strokes and coating method
The first plane color, painted after a deep color in the similar content outline edge map. As a result, colors have ups and downs, not monotony.
2, multicolor contact method

3 、 color matching
Take two or three or four similar colors (warm colors or cool colors). At the periphery of a circle first coated with deep color, with lighter crayons in turn, was painted to cover the original deep color 1/2. As a result, the color can be graded evenly, from deep to shallow or with a certain sense of three-dimensional.
4, strong contrast method
Contrast pictures with contrasting colors to improve visual impact and enhance screen effects.
5, drawing and line drawing method
This method is relatively simple, mainly for the background or a part of the decoration. Through the same or more colors of crayons, a little or line to decorate the picture, you can get unexpected picture effect.
6, thin painting
The use of this method requires some basic skills in painting, when the little boy’s hair, make full use of the white paper, with black from deep to shallow, slowly leaves a little white, so that the hair is very realistic.
Cover the whole paper with bright crayons and cover it with a black or dark color. Then, with a scraper or a hard object, make an image. There is another effect.
8 、 crayon and gouache combination
Crayon does not melt in water, you can draw crayons, draw lines, gouache, color method, highlighting the effect of the screen. Crayon is an ideal tool for children to learn colors, in fact, crayon painting methods are many, many picturesque paintings in different colors will have different effects
Knife scraping method
It is a way of damaging the paper to make a special effect by using a pencil with a pencil sharpener.
Before coloring on the paper with a knife or light or heavy, or wide or narrow shave, damage to the part of the paper, after coloring a little heavier than the surrounding color image. This is because the bristles are so strong in color that they become heavier. It shows blurred images or vague details, and works better.
For the knife coloring process, much water will produce heavy water marks, little floating color was scraped and will produce marks brighter details, processing method. After another in the color is completely dry, scraping white light with a knife, or intermittently scraping, to show the bright line, bright light or small bright surface, blinking lights and winter snow falling, the true mingled with the false natural and interesting.
Paint with crayons or oil bars before coloring. When you paint, you can use your pen as bold as possible. Used to describe sparse leaves, night lights, complex crowd, etc., are more effective, you can receive twice the result with half the effort.
Use absorbent paper (filter paper or raw rice paper) and color when wet. According to the effect of the need, the suction weight, size can be flexible, but also can suck the color after the application of light color. With a sponge or squeeze the water paint brush, wash some parts of the screen also do not taste, and have the same trick.
Sometimes the painting landscape painting in the drizzle weather, the picture color is a natural rain wet, fascinating. Sometimes water is sprayed before coloring, and sometimes water is sprayed at the end of the dry color. Spray bottle to choose spray mist like good, water point is too big, easy to destroy the picture effect.
The color at the end of dry sprinkle fine salt, like snowflakes texture taste dry after. Sprinkle salt, depending on the degree of wet and dry screen, the party lost its function. On the screen to sprinkle salt on the density of randomly scattered, come to naught.
In a glass or plastic coated surface smooth paper, draw in color, and then put the paper on the cover, printed woodcut, printed a beautiful picture sticky texture, it is quite natural. This effect is easy to use with fine lines of watercolor paper. It can be used as a main tool for printing. It can become an interesting watercolor painting. Some local printing methods, most still rely on the brush completely.
1, dry drawing and wet drawing
Dry drawing is a multi – layer painting. The method of layer coating is applied on the dry base color, and the effect of infiltration is not required. The utility model can be painted more easily and easily, and is easy to master, and is suitable for beginners to practice. Sure, the Zhe body structure performance and the level of rich color is dry drawing skills. But dry painting can not only in the “dry” characters to make an article, the picture must still make people feel full of water, wet marks, avoid dry, dry problems. Dry painting method can be layered coating, cover color, color, dry pen and other specific methods.
The coating is dry in the dry and then overlap, coloring colour, a layer of overlapping color objects. In the picture painted a number of layers, in some places, some places can be over two times, three times or more, but not too many times, so as not to lose a sense of transparency color grey dirty. Layer painted like colored work overlap, prior to the expected background color mixing effect, this point can not be ignored.
The mask color: it is actually a kind of stem overlap method, mask color area, such as in the picture a few pieces of color is not unified, with the method of cover color, uniform colors make masks again. A certain color is too warm, cover a cool color, change its cooling and warming properties. Cover the color should be more bright color, thin painted, shop over, generally do not return pen, or bring the background color will dirty. This is often used during shading and the final adjustment of the screen.
The ground color: color is dry ground in the adjacent color after drying from the next color, not color infiltration between each color itself can also increase the wet paint, change. The feature of this method is that the outline of the object is clear and the color is bright.
The pen nib: less water color pen, prone to feibai; water is full quickly painted in coarse grain paper, will produce feibai. Show flash or soft, see, just wait effect, often use dry pen method.
Wet drawing can be divided into two kinds of wet overlap and wet color.
The stick can cover and a palette of materials, painting techniques can look like painting repeatedly add cover, use the stick paint mainly in the direct comparison of color and use his strong touch pen, oil painting stick rub, rub, can also be a layer of color in the use of other tools to scrape the it will also appear a little effect after dissolved by surprise.
An oil painting stick is a rod shaped material made from a special mixture of pigments, oils, and waxes. The use is very simple, you can draw directly on the painting, or mixed with color, layer coating, scraping, layering and other techniques to enrich its effect. By using these techniques individually or in combination, you can draw your own style. Unlike oil paints and watercolors, the oil stick is a solid pigment, without preparation for mixing or toning. Once you have the urge to paint, you can start writing at once.
Oily crayons generally have two kinds of hard and soft. If the stick is too soft and will stick to your finger, it is difficult to use. This soft oil crayon is suitable for thick coating, but they can not achieve the fine effect needed for mixing and coating. Usually, the “oil” of a soft crayon will smear the paper or get the paper out. However, oil stick is a kind of perfect hardness of oil crayon, soft and hard moderate, reasonable. There is no weakness for soft crayons.
1, painting different effects: Crayon will not be water paste, painted out there will be soft, casual feeling. And according to different paper crayons, the effect will be different. For example, a rough crayon on paper, though grainy, has a very saturated color. Oil painting stick, as the name suggests, is able to paint like oil paintings. The strokes of the oil bar are a little thinner than the crayons, and the color is a little bright. Without crayons, they feel very retro.
2, material and characteristics are different: oil painting stick is not afraid of water, high temperature resistance, more stable. And crayon, in case of high temperature will turn, and the color is very dark, easy to dry, will crack.
