Colored lead can be divided into water-soluble and waxy. Among them, water-soluble colored lead is commonly used, which has the property of being soluble in water, has a sense of infiltration when mixed with water, and can also be rubbed with fingers to produce a soft effect.
Colored lead is characterized by portability, rich colors and quick and concise expression.
Basic technology of colored lead?
(1) flat coating method?
Use colored pencils to arrange pencil lines evenly to achieve the same color effect.
(2) overlapping color method?
Use colored pencils to arrange pencil lines of different colors, and the colors can be overlapped and varied.
(3) Water-soluble stunning method?
Based on the solubility of water-soluble colored lead in water, the colored lead thread is fused with water to achieve the effect of blooming.
How to draw colored lead?
Colored pencils are not suitable for large-area monochrome use, otherwise the picture will appear dull.
In the actual painting process, colored pens are often used in conjunction with other tools, such as combining with pen lines, sketching the outline of space and objects with pen lines, and coloring with colored pens; Combined with marker pen, use marker pen to draw the big tone of the picture, and then use color lead superposition method to describe the depth; Combined with watercolor, it reflects the effect of color blooming.
Colored pencils have their own unique strokes, which are light and have a strong sense of lines. They can be drawn by hand or ruler. Attention should be paid to the handling of the relationship between reality and reality and the embodiment of the aesthetic feeling of lines when painting.
Colored lead technology is one of the rapid expression technologies.
Color lead painting technology
Materials, first of all, we should realize that colored pencils are translucent materials, and their production is very different from sketch pencils made of graphite and clay in different proportions. Domestic colored lead is mostly wax-based, which is not easy to form delicate style and sharp boundary, but it belongs to a kind of auxiliary material. Most foreign colored pens are carbon-based and water-soluble, but water-soluble colored lead is generally difficult to form a smooth color layer with many spots, so it is more suitable for coating-dissolving-coating to form mottled effect.

2. Painting method, the painting method of colored pen can reflect a person's patience and delicacy. The difficulty of colored pen lies in its simple basic drawing method, namely plane drawing method and plane arrangement method. Don't be impetuous, or the things that come out will be just like children's paintings. When arranging the cable, you should arrange it honestly, and draw the fishing line closely to form a color block, which will have a stable and lasting effect.
3. Coloring sequence, because it is a translucent material, it should be done one by one in the order of light color first and then dark color, and it should not be rushed. Otherwise, the picture is easy to appear dark and lacks depth. In the last few times of coloring, we can press the pigment particles onto the paper, the colors can be slightly mixed, and the surface is smooth and moving.
4. The best choice of medium and drawing paper is to have a certain thickness of cardboard, because you can use sandpaper and knife to scrape the bright part later, which is particularly touching. If you want to draw homework because the methods and materials described above take a long time (more suitable for painting fine works), another material is translucent paper, such as sulfuric acid paper.
Because it can be painted on both sides, it can be delicate and smooth in a short time with a piece of white paper as the bottom after painting.
5. modify. Colored lead is different from pencil for sketch, and it is difficult to remove with ordinary rubber. You use a sand eraser to modify the ink lines, among which the domestic ones are more suitable for special effects, while the Huibaijia and Shide buildings are more exquisite and can be modified slightly.
