How Color Theory works

The Color Picker converts between three major color formats: HEX (hexadecimal web colors), RGB (red, green, blue channels), and HSL (hue, saturation, lightness). It also generates color harmony suggestions based on color wheel relationships like complementary (opposite), analogous (adjacent), and triadic (120 degrees apart) colors.

Formula

HSL to RGB conversion uses the formula: C = (1 - |2L - 1|) * S, with hue determining the color wheel position

Watch out

Common mistakes

  • When designing for accessibility, ensure a contrast ratio of at least 4.5:1 between text and background colors. Use complementary colors for strong visual impact, and analogous colors for harmonious, cohesive designs.
