Free Color Palette Generator

Generate Harmonious Color Palettes

This tool generates color palettes using established color theory principles — complementary, analogous, and triadic schemes — giving you a starting point of colors that are mathematically guaranteed to work well together, rather than a purely random and potentially clashing set.

Understanding Color Harmony Schemes

• Complementary — two colors positioned directly opposite each other on the color wheel (180° apart), creating maximum contrast and vibrant, energetic combinations.
• Analogous — colors positioned next to each other on the color wheel (typically within 30-60°), producing a naturally cohesive, harmonious feel often found in nature.
• Triadic — three colors evenly spaced around the color wheel (120° apart), offering strong visual contrast while still feeling balanced and intentional.

How This Tool Works

The generator picks a random starting hue, then calculates the other colors in the palette using precise angular offsets on the HSL (Hue, Saturation, Lightness) color wheel — 180° for complementary, small offsets around the base hue for analogous, and 120° increments for triadic. This mathematical approach to color relationships is the same principle professional designers use, just automated and randomized for quick inspiration.

Common Uses

• Web and UI design — quickly generating a cohesive color scheme for a website or app.
• Branding and logo design — exploring color combinations for a brand identity.
• Data visualization — choosing distinct, harmonious colors for charts and graphs.
• Art and illustration — finding fresh color combinations for creative projects.
