A color wheel is a circular diagram that organizes colors by their chromatic relationship. First created by Isaac Newton in 1666, it maps hues around a circle so you can see which colors harmonize, contrast, or complement each other. Keynou's digital color wheel is built for RGB screens and interactive design work.

Drag the active gizmo around the wheel to pick a hue and saturation, or type a HEX code directly. Adjust the saturation and lightness sliders, then choose a palette type like complementary, triadic, or analogous. Click any color swatch to copy HEX, RGB, or HSL instantly.

Complementary colors sit directly opposite each other on the color wheel, 180 degrees apart. Pairs like red and cyan, blue and orange, or yellow and purple create maximum contrast and make each color appear brighter when placed side by side.

Analogous colors are three colors that sit next to each other on the wheel, usually within 30 degrees. They feel natural and harmonious because they share a common base hue, making them ideal for calming website designs and nature-themed artwork.

Triadic colors are three hues evenly spaced 120 degrees apart on the color wheel. This scheme delivers bold, balanced contrast without clashing, making it popular for illustrations, posters, and vibrant brand palettes.

Tetradic (or square) palettes use four colors evenly spaced 90 degrees apart. They offer the richest variety of any harmony type. Let one color dominate and use the other three as accents for best results in complex designs.

A monochromatic scheme uses a single base hue with different shades, tints, and tones. It creates a clean, cohesive look because every color comes from the same family. This is one of the safest choices for professional branding and user interfaces.

A shade is a hue mixed with black to make it darker. A tint is a hue mixed with white to make it lighter. A tone is a hue mixed with grey, which mutes the color without making it look as pastel as a tint.

HEX is a six-digit code web browsers use for colors. RGB defines color by red, green, and blue values from 0 to 255. HSL describes color by hue, saturation, and lightness, which is more intuitive for designers when adjusting a color.
