Color mixing by three primary colors

Quick answer：

Color mixing by three primary colors refers to the process of combining red, blue, and yellow, which are considered the primary colors in subtractive color mixing. These colors can be mixed to create secondary colors (green, orange, purple), tertiary colors (red-orange, red-purple, blue-green, blue-purple, yellow-green, yellow-orange), and a wide range of other hues. This concept is fundamental in art, design, and the production of various media like paints and dyes.
