The Color Wheel: How It Works + Interactive Guide

The color wheel is a circular diagram that organizes colors by their relationships. It shows how colors connect, which pairs create contrast, and how to build harmonious palettes. Understanding the complementary colors relationship is central to using the color wheel effectively.

What Is a Color Wheel?

The color wheel arranges hues in a circle

A color wheel arranges hues in a circle so that relationships between colors are visible. Primary colors sit at key positions; secondary and tertiary colors fill the gaps. The wheel makes it easy to find complementary, analogous, triadic, and other color schemes.

Primary, Secondary, and Tertiary Colors

On the RYB wheel, red, yellow, and blue are primary. Orange, green, and purple are secondary. Tertiary colors (red-orange, yellow-green, etc.) sit between primary and secondary. Each segment has a complementary color on the opposite side.

Complementary Colors on the Wheel

Complementary colors sit 180° apart. Draw a line through the center from any color—the color at the opposite end is its complement. This creates maximum contrast. Red and green, blue and orange, yellow and purple are the classic pairs.

Other Color Relationships

Split-complementary uses one color plus the two adjacent to its complement. Triadic uses three colors 120° apart. Analogous uses adjacent colors. Learn more in our split-complementary and triadic guides.

RYB vs RGB vs CMYK

RYB (red, yellow, blue) is for traditional art and paint. RGB (red, green, blue) is for screens and additive color. CMYK (cyan, magenta, yellow, black) is for print. Complementary pairs differ slightly between models, but the principle of opposites is the same.
