How to adjust the color of gouache? For example, red+yellow = orange

The color of gouache is a kind of color blending according to the needs of the picture, which requires the color to produce gorgeous, soft, bright and rich artistic effects on the picture. Color matching is based on correct observation and understanding of the color relationship of objects. When mixing colors, you can't look at one piece in isolation, adjust one piece and draw one piece. We should consider the overall hue and color relationship, and decide each color from the whole. The colors of gouache sketch are not easy to connect. On the basis of clarifying the relationship between colors, try to adjust the colors of several large color blocks and prepare for redrawing. Don't be divorced from the whole, look at one piece, adjust one piece, draw one piece, and adjust one piece for another. The color of gouache painting is dark when wet, light after dry, and the wet and dry changes obviously. If more powder (white) is used in color matching, or if a thicker color layer has been drawn, and then colored for painting, the dry and wet changes of the pigment will be more significant with paper with strong water absorption. It is difficult to make a correct estimate of gouache color matching. It is difficult to connect, cover and modify colors. This is an obvious feature and difficulty of gouache painting. Pay special attention to this problem when you are a beginner. So we should draw heavy colors at the beginning. Generally speaking, when painting is wet, the color is wet. After painting in one breath, the color relationship is easy to master. If the color is dry, connect the colors and cover them. Pay attention to the wet and dry changes of the colors.

Gouache needs more colors first.

Because I didn't know how to mix colors at first, I had to rely on ready-made colors. If the color is less, it will be dirty if I adjust it too much.

It is recommended to buy all colors and use them directly after painting. This is the first step for beginners. For example, if you draw a beer bottle with olive as the main color, there is no problem. Without this color, you will be in trouble and need to adjust. .......

Several colors with the largest amount of gouache.

White, lemon yellow Blue, scarlet, gray (beginners still buy gray, because it's not easy to tune, so you don't have to buy it when you're high)

Common pigment tools:

1. Oil painting knife is used to dig paint (bottles).

2. The color palette is used for coloring; The pigment box is used to hold pigments; Toner box, with a layer of sponge inside, dipped in water and placed in the paint box to prevent the paint from drying out. But you'd better not get wet, or your paint will get dirty. Spray some water after painting.

Toner cartridges are not recommended. They are all packed in tin cans, and you can squeeze as much as you want (it's too luxurious, but it's convenient to smoke).

Second, the color is cold and warm

Red: vermilion (warm) rose (cold)

Yellow: medium yellow (warm) khaki (cold)
