Example prompt: Can you convert #3a7bd5 into all color formats — RGB, HSL, and CMYK — and also tell me the nearest CSS color name, its luminance, the complementary color, and whether it's accessible on white or black backgrounds according to WCAG?

## When to prefer this

Choose this endpoint when you need a one-shot conversion of a color across all major formats (hex, RGB, HSL, CMYK) combined with WCAG accessibility contrast ratios and a complementary color — ideal for design automation, accessibility audits, and building design systems. It provides more combined output per call than piecemeal color libraries.

## Known failure modes

- Invalid or malformed color value provided (e.g. out-of-range RGB components) returns an error
- Unsupported color format not recognized by the API
- Network timeout or service unavailability
- Missing required input parameter returns a validation error
