Color

Blend two colors with intermediate steps and explore complementary/analogous/triadic relationships

Pick two colors and a step count to generate a gradient of intermediate colors between them, handy for building a data-visualization scale or a set of hover/transition states without picking each shade by eye. Blending happens either in RGB space, a straightforward per-channel average that can look slightly muddy or desaturated in the middle when the two endpoints are very different hues, or in HSL space, which interpolates around the hue wheel and tends to hold saturation better across the transition. A single base color also drives complementary (opposite on the wheel), analogous (nearby hues), and triadic (evenly spaced) harmony suggestions, all computed from hue rotation while holding saturation and lightness steady. It blends exactly two colors at a time; chaining several blends is a manual step if you need a multi-color gradient path.

How to use Color Blender

  • 1.Pick two colors and choose a step count to generate a smooth gradient of intermediate colors for a design palette or data visualization scale.
  • 2.Enter one base color and switch to complementary, analogous, or triadic mode to see harmonious color combinations for a UI theme.
  • 3.Copy any intermediate blend step as HEX or RGB to use as a hover state or transition color between two brand colors.

Frequently asked questions

What color space is used for blending?
Blending is done in RGB by default, which is simple but can produce muddy midpoints — for perceptually smoother blends between very different hues, expect the middle steps to look slightly desaturated.
Is my color data sent anywhere?
No, all blending and relationship calculations happen locally in your browser.
How are complementary/analogous/triadic colors calculated?
They're derived from the base color's position on the HSL color wheel — complementary is 180° opposite, analogous are adjacent hues, and triadic are evenly spaced 120° apart.
Can I blend more than two colors at once?
No, this tool blends exactly two colors at a time — chain multiple blends manually if you need a multi-color gradient path.
