Color wheel diagram explanation

Quick answer：

The color wheel diagram is a visual representation of colors arranged according to their chromatic relationships. It is used in various fields such as art, design, and color theory. The diagram typically includes primary, secondary, and tertiary colors, with the primary colors being red, blue, and yellow. These primary colors cannot be created by mixing other colors but can create all other colors when mixed together. The color wheel also illustrates the relationships between complementary colors, analogous colors, and triadic colors, which are important in color theory for creating harmonious color schemes.
