How this service works
Color conversion for AI agents — give a color as hex, rgb(), hsl(), or a CSS name → every representation (hex, rgb, hsl) plus the matching/nearest CSS color name. Pay-per-call in USDC via x402 — no signup, no API key. Use for theming, design/UI generation, and normalizing colors.
Output
Returns all color representations for the input color: hex code, rgb() string, hsl() string, and the matching or nearest CSS color name.
Example use cases
Generate accessible color palettes for UI themes
“I'm building a dark mode for our app. Take these brand colors—#FF6B35, #004E89, and #F7B801—and convert them all to RGB and HSL so I can create CSS variables. Also tell me what standard CSS color names are closest to each one.”
Normalize user-submitted color inputs
“Our design tool lets users paste colors in any format. Take these three inputs: 'rgb(147, 51, 234)', 'hsl(45, 93%, 58%)', and 'crimson'—convert them all to hex codes and give me the official CSS name for each one.”
Match design mockup colors to web standards
“I'm working from a Figma design that specifies colors in hex. Convert #A78BFA and #EC4899 into all color formats (hex, RGB, HSL) and find me the closest named CSS colors so developers can use the standard names in our stylesheets.”
