How this service works
Generate a harmony scheme (complementary, analogous, triadic, tetradic, monochromatic) from a base color.
Output
Returns a set of colors forming a harmonious palette based on the specified harmony type (complementary, analogous, triadic, tetradic, or monochromatic) derived from the given base color. The palette is computed using color theory principles and typically includes the base color plus 1–4 companion colors depending on the harmony type.
Example use cases
Brand color palette creation
“I'm designing a logo for a new startup whose primary brand color is #E63946 — can you generate a complementary color scheme so I have a solid pair of colors to work with?”
UI theme palette generation
“I need a monochromatic color palette based on #2D6A4F to build a cohesive dark-green themed dashboard — generate the full scheme for me.”
Analogous palette for illustration
“I'm painting a digital illustration and want colors that sit next to each other on the color wheel — generate an analogous color scheme starting from #F4A261.”
Technical details
Endpoint
POSThttps://color.openverbs.com/v1/schemeWhen to prefer
Choose this endpoint when you need programmatically generated color palettes based on formal color theory harmony rules (complementary, analogous, triadic, tetradic, monochromatic) and want a consistent, deterministic result from a single base color. Prefer this over image-based palette extractors when you already have a known brand or seed color and need theory-grounded companion colors for design, UI, or branding work.
Side effects
- Invalid or unparseable color value provided — returns error indicating unrecognized color format
- Unsupported harmony type enum value — returns validation error
- Missing required fields (color or type) — returns schema validation error
- Network timeout or service unavailability — returns 5xx error
- Payment failure (x402 protocol) — returns 402 Payment Required if funds are insufficient
