Color wheel and its meaning

Quick answer：

A color wheel is a circular chart representing primary, secondary, and tertiary colors. It is used in art, design, and color theory to understand color relationships and harmonies. The primary colors are red, blue, and yellow, and they are mixed to create secondary colors (green, orange, purple) and tertiary colors (mix of primary and secondary colors). The color wheel also shows complementary colors, which are opposite each other and create vibrant contrasts when paired.
