How this service works
Generate a coordinated palette from a base color using a named color-theory scheme: complementary (2 colors), analogous (3), triadic (3), tetradic (4), split-complementary (3), or monochromatic (5 lightness variants). Returns each color in hex, rg...
Output
Returns a set of colors derived from the base color according to the chosen scheme: 2 colors for complementary, 3 for analogous/triadic/split-complementary, 4 for tetradic, and 5 lightness variants for monochromatic. Each color is returned in hex and RGB format.
Example use cases
Example prompt
“Generate a triadic color palette based on the color #E63946 — give me all the resulting hex and RGB values.”
Technical details
Endpoint
POSThttps://agent402.tools/api/color-paletteWhen to prefer
Use this endpoint when you need algorithmically correct color-theory-based palettes from a single base color, especially when you need a specific named scheme (complementary, triadic, etc.) rather than a subjective or AI-generated palette. Ideal for design tools, UI theming, brand palette generation, and any workflow requiring mathematically harmonious color sets.
Side effects
- Invalid or unparseable base color string — returns error indicating bad color input
- Unknown or misspelled scheme name — returns error listing valid scheme options
- Missing required fields (color or scheme) — returns validation error
- Malformed request body — returns 400-level error
