How this service works
Color conversion: hex or rgb() input to hex, RGB, HSL, approximate relative luminance and best text contrast (black/white).
Output
Returns the input color expressed in hex, RGB components, HSL (hue/saturation/lightness), an approximate WCAG relative luminance value, and a recommended text contrast color (either black or white) for optimal readability.
Example use cases
Accessibility contrast check for UI
“I'm designing a button with background color #E74C3C — can you tell me if black or white text will be more readable on it, and give me the luminance value?”
Design token format conversion
“I need the HSL and RGB equivalents of rgb(34, 139, 34) for my design system — can you convert it and also give me the hex code?”
Dynamic theme text color selection
“My app lets users pick a custom background color. Given the hex #1A1A2E, what text color — black or white — gives better contrast, and what's the luminance?”

Endpoint
GEThttps://api.aventtech.com/convert/colorWhen to prefer
Use this endpoint when you need a quick, authoritative multi-format color conversion including accessibility-oriented outputs (relative luminance and black/white text contrast) in a single call, especially for UI/UX, design systems, or accessibility compliance workflows. Prefer it over manual computation or generic color libraries when you need a reliable API call without local dependencies.
Side effects
- Missing or malformed 'color' query parameter returns an error
- Unsupported color format (e.g. named colors like 'red' or HSL input) may not be accepted
- Out-of-range RGB values (e.g. rgb(300,0,0)) may return an error
- Payment failure or insufficient USDC balance blocks the request
