Color Palette Generator
Generate complementary, analogous, and triadic palettes from any base color.
About Color Palette Generator
Color Palette Generator builds harmonious color schemes from a single base color using five classical color-theory rules: monochromatic (a five-step lightness ramp from the same hue), analogous (the neighbors on either side of the wheel), complementary (the opposite color across the wheel, with tonal variations), triadic (three evenly-spaced hues plus tonal variants), and tetradic (four evenly-spaced hues plus tonal variants). Each scheme returns five swatches so you have working hover/active states without further tweaking. It is the fastest way to bootstrap a palette before refining it by hand.
Worked example: pick #3b82f6 (a mid blue) and the complementary scheme returns its counterpart in orange alongside tonal variations of both; the analogous scheme returns adjacent blues and violets; the triadic scheme adds a green and a deep pink. Each swatch shows its hex value; click any swatch to copy it to your clipboard for pasting into a stylesheet, Figma, or a CSS variable definition.
Color harmony is a starting point, not a finished decision. The wheel-based rules produce technically harmonious combinations, but a production palette usually needs adjustments for contrast (so text stays readable), brand fit, and the desaturated supporting shades a real interface needs (neutral grays, semantic colors for success / warning / error). Treat the generator as a seed: pick a rule that fits the mood, copy the swatches that work, and refine by hand. For accessibility, pair each text-and-background pair with the WCAG Contrast Checker before committing — harmonious is not the same as readable.
