How to adjust the color of red brick with color paste?

Red pulp+yellow pulp is dominant. White and black are auxiliary colors. These four kinds of medium color pastes will do. If you want to paint the wall yourself, you can first decide the color of your room, whether it is cold or warm, then choose the color paste according to the determined color, choose the amount of color paste according to the amount of room, see what color you need, and then ask the color master how much you need. Some colors can't be adjusted by one paste, and you need several paste tones to adjust them to meet your needs.
