How this service works
Build a colour palette from one hex colour: complementary, analogous, triadic, split-complementary and tetradic harmonies (hue rotations at the same saturation and lightness), plus six shades from light to dark, all as hex codes, with the base colour's HSL. Use for UI themes, charts, brand kits or slide decks; to check text readability on a colour use color_contrast.
Output
Returns a JSON object containing: the base hex color, its HSL breakdown (h, s, l), arrays of hex codes for complementary, analogous, triadic, split-complementary, and tetradic harmonies, and a shades array of six hex codes ranging from light to dark — all computed at the same saturation and lightness as the base color.
Example use cases
Brand kit color expansion
“I want to build out our brand color palette from our primary color #E84855 — give me all the harmonies like complementary, triadic, and analogous colors plus shades from light to dark so our designers have a full kit to work with.”
UI theme generation for a dashboard
“I'm designing a dashboard and my base color is #2D6A4F — can you generate the full color palette with harmonies and shades so I can pick accent and background colors for the UI theme?”
Chart color scheme from brand color
“For our data visualization charts I need a set of visually distinct colors — start from #F4A261 and give me the triadic, tetradic, and split-complementary harmonies so the chart lines don't clash.”
Technical details
Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/color/palette?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to derive a harmonious set of colors from a single known hex value — especially for UI theming, brand kit creation, chart color schemes, or slide deck design. It is superior to manual HSL math or generic color tools when you need all major harmony types plus a shade ramp in a single call. For checking whether two specific colors have sufficient contrast for readability, use the color_contrast endpoint instead.
Side effects
- Invalid or malformed hex color (e.g. missing # without short-form, letters outside 0-9A-F) returns an error
- Missing required 'color' parameter returns a 400-level error
- Edge case: pure white (#ffffff) or pure black (#000000) may yield degenerate shades with no visible variation
