How this service works
Zach Riehn's lab: an about-me and portfolio, a news desk, The Atelier for AI experiments, Launch Lab for XRP research, and Fracture for games.
Output
Returns a JSON object containing the hex code, RGB array [r,g,b], HSL array [h,s,l], the recommended best text color ('black' or 'white'), boolean WCAG AA pass/fail flags for both black and white backgrounds, and the numerical contrast ratios against both black and white.
Example use cases
Accessibility audit for brand color
“I'm using the color #FF6B35 as my primary brand color — does it pass WCAG AA contrast on a white background, and what text color should I put on top of it?”
UI design color format conversion
“Convert the color 'dodgerblue' to its exact hex, RGB, and HSL values so I can use it consistently across my design system.”
Pick readable text color for dynamic background
“My app generates user profile cards with background color #4B0082 — should I use black or white text on top of it to keep it readable?”
Technical details
Endpoint
GEThttps://cocoeatsai.com/area4/agent/tools/color?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a quick, cheap color utility that simultaneously handles format conversion (name/hex to hex/RGB/HSL) AND accessibility scoring (WCAG AA contrast ratios) in a single call. Ideal for UI agents, design automation, or accessibility checkers that need to validate color choices without running a heavier color library locally.
Side effects
- Unrecognized or malformed color string returns an error or unexpected hex output
- Missing 'value' query parameter may result in a default or error response
- Non-standard color names not in the parser's dictionary may fail to resolve
- Edge case colors near the contrast threshold may have borderline WCAG results
