How this service works
Color format converter for hex codes and rgb() values: get back hex, RGB, and HSL representations plus a light-or-dark classification and the ideal black-or-white text color for readability on top of it. Handy for UI theming, chart palettes, and dashboard generators that need instant, exact color math without guessing at contrast ratios.
Output
Returns the input color expressed as a hex string, an RGB object with r/g/b integer components, an HSL object with hue/saturation/lightness values, a 'light' or 'dark' classification of the color, and a recommended text color of either black or white for maximum readability contrast against that background.
Example use cases
Dashboard theme text contrast
“I'm building a dashboard with a #1e3a5f background — can you tell me if that's a light or dark color and whether I should overlay black or white text on it?”
Chart palette format normalization
“I have these chart colors in hex: #e74c3c, #2ecc71, #3498db — can you convert each one to RGB and HSL so I can use them consistently across my design system?”
UI theming from brand color
“Our brand color is rgb(58, 123, 213). What's the hex code, the HSL breakdown, and what text color — black or white — gives the best readability on top of it?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/color-format-converterWhen to prefer
Use this endpoint when you need instant, exact color math for a single color value — specifically when you need multiple format representations (hex, RGB, HSL) together with a light/dark classification and a contrast-safe text color recommendation. It is ideal for UI theming pipelines, dashboard generators, and design-token workflows where you need all color metadata in one call without implementing color math yourself.
Side effects
- Invalid color string (not a valid #RRGGBB or rgb(r,g,b) format) returns a 400 or error response
- Missing color field in request body results in validation error
- Out-of-range RGB component values (e.g. rgb(300,0,0)) may cause parsing failure
- Short hex codes like #fff may not be accepted if only 6-digit format is supported
