Pick one color, get 7+ harmonious palettes. Complementary, analogous, triadic, and more.
A palette generator derives colors that work together from a single base color. HexColor Pro applies seven harmony rules — complementary, analogous, triadic, split-complementary, tetradic, monochromatic, and shades — and returns ready-to-copy HEX values for each palette.
Two colors opposite each other on the color wheel. Creates high contrast and vibrant combinations. Great for call-to-action buttons and accent elements.
Colors next to each other on the wheel. Creates harmonious, natural-feeling palettes. Perfect for backgrounds and cohesive designs.
Three colors evenly spaced on the wheel (120° apart). Balanced and vibrant with good contrast. Use one dominant, two accents.
A base color plus the two colors adjacent to its complement. Less tension than straight complementary, but still visually interesting.
Four colors in two complementary pairs. Rich palette with lots of variety. Use one dominant, rest as accents.
Variations of a single hue (different lightness/saturation). Clean, elegant, and easy to get right. Great for minimalist designs.
From light tint to dark shade of the same color. Useful for UI elements like buttons, cards, and text hierarchy.
Harmony comes from a consistent relationship on the color wheel plus a deliberate contrast budget. Complementary, analogous, and triadic schemes each fix one kind of relationship; a usable palette then adds one accent and enough lightness separation for text and UI states.
Most production interfaces settle on five to seven: one or two neutrals for surfaces and text, one primary, one accent, and one or two semantic colors for success and error. A larger token set is fine, but the visible colors on one screen stay small.
It is a proportion guideline: 60% of the visual area in a dominant color, 30% in a secondary, 10% in an accent. It keeps a palette from feeling evenly weighted, and it maps cleanly onto CSS custom properties for background, surface, and accent.
