How this service works
Color palette from a hex color - complementary, split, analogous, triadic and tetradic harmonies, a 50 to 950 scale, tints, shades and WCAG contrast ratios
Output
Returns the input color normalized to hex, RGB channels (r, g, b 0–255), HSL values (hue in degrees, saturation and lightness in percent), a 50–950 tonal scale with tints and shades, color harmonies (complementary, split-complementary, analogous, triadic, tetradic), WCAG contrast ratios against black and white, and a recommended readable text color for overlay use.
Example use cases
Brand color system generation
“I'm building a design system around our brand color #E84C3D — can you give me the full palette with complementary, analogous, and triadic harmonies, a 50–950 tonal scale, and the WCAG contrast ratios so I know what text colors are accessible on it?”
Accessible UI color check
“I need to check if my button color #28A745 is accessible — can you pull the WCAG contrast ratios on white and black backgrounds, and also give me the tints and shades for hover and active states?”
Tetradic palette for a mood board
“I'm putting together a mood board and want a tetradic color scheme based on #7B2D8B — can you generate all the harmonies and the full tonal scale so I have plenty of options to work with?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/design/palette?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, ready-to-use color palette derived from a single hex color, especially when you need WCAG accessibility data alongside design harmonies and a full tonal scale. It is ideal for design-system automation, brand color expansion, and accessibility auditing in a single call rather than stitching together multiple color-theory tools.
Side effects
- Invalid or missing hex color parameter returns an error
- Malformed hex codes (e.g. wrong length, non-hex characters) may return a validation error or unexpected results
- Very short hex codes (1–2 characters) may not be interpretable
- Network or upstream service errors may result in HTTP 5xx responses
