Extended data:

Color matching principle: as few kinds of pigments as possible, including black and white. Generally, you can mix up to four colors. Adding more than the fifth color can only increase black and gray, and the contrast color of colors together is black and gray. If the colors are properly matched, there will be a feeling of moistening. The feeling that the paint coated on the canvas penetrates into the picture and retreats into the space. On the contrary, it is not good to appear dry and floating.
