What are the methods of color matching?

Composite color: red+yellow = orange+blue = purple+yellow+blue = green.

Intermediate color: yellow+orange = orange+green = brown?

Contrast color refers to the collocation of two colors with extremely obvious visual differences, thus causing a stronger visual impact effect. For example, the six colors of red, orange, yellow, green, blue and purple can produce strong contrast effects with black and white respectively, and can also produce different degrees of contrast effects with each other, such as red and yellow, red and blue, red and green, blue and green, yellow and blue, Rayna Sue, orange and purple, orange and yellow and so on.

On the basis of the same hue, more colors are extended from lightness and saturation respectively. At this time, these color features can be used to match the same color system. The so-called collocation of the same color system refers to the collocation of different shades or shades in the same color system, which will have a strong layering effect when used in clothes. Under the current popular aesthetic trend, it is more textured than contrast color.

When two or more colors are mixed and matched in different proportions, different colors will appear. If you put them in a computer, you can change them into the same color by inputting some proportional values. But in the manual operation of pure painting, it is impossible to bring out exactly the same two colors, only similar colors. Moreover, in painting, it is not necessary to call out the same colors as the actual objects, and the focus is on the collocation of various colors in the picture, rather than the similarity of colors together.

If there are more than three layers, the principle of color gradient should be followed to achieve natural harmony.
