What this tool does

Generates an analogous color scheme — three colors positioned 30° apart on the color wheel — from any base color you enter, using HSL hue rotation while keeping saturation and lightness constant.

How to use it

Pick a base color with the color swatch or type a hex code directly. The three swatches — labeled −30°, Base, and +30° — update immediately; click the copy icon on any swatch to copy its hex value.

Worked example

The default base color #3b82f6 (a blue with hue ≈217°, saturation ≈91%, lightness ≈60%) produces #3bdff6 at −30° (a cyan) and #513bf6 at +30° (a purple) — three neighboring hues that share the base color's saturation and lightness.

Formula

Each neighboring color is generated in HSL space: hue is shifted by −30° and +30° from the base hue, while saturation and lightness stay exactly the same as the base color. The result is converted back to hex for display and copying.

Why analogous schemes feel harmonious

Colors within about 30° of each other on the color wheel share enough hue similarity that they read as naturally related rather than clashing, which is why analogous palettes are common in nature — sunset skies, autumn leaves — and in designs that want a cohesive, low-contrast mood rather than the strong tension of a complementary or triadic scheme.

Limitations

This generates colors from pure hue rotation only — it doesn't check contrast ratios for text accessibility (WCAG), doesn't suggest which of the three should be dominant, and the ±30° step is fixed rather than adjustable, so you can't widen or narrow the spacing between hues.

Scope, sources and privacy

Analogous color theory is a standard color-harmony model used in design education and practice. The colors are computed entirely in your browser using RGB/HSL conversion math; the color you enter is never uploaded.

Frequently Asked Questions

What is an analogous color scheme?
Colors that sit next to each other on the color wheel, typically within 30° of hue — they naturally look harmonious together.
Where are analogous schemes commonly used?
They work well for backgrounds, gradients and designs that need a cohesive, low-contrast feel — think sunsets or nature-inspired palettes.
How many colors does this generate?
Three — your base color plus one 30° to each side on the color wheel.
