How this service works
Convert a hex color to RGB, HSL, HSV and CMYK with CSS strings and relative luminance, exactly.
Output
Returns a structured object containing the input hex, RGB (r, g, b), HSL (h, s, l), HSV (h, s, v), and CMYK (c, m, y, k) numeric values, CSS-ready strings for RGB and HSL, the relative luminance value, and optional metadata like source and summary.
Example use cases
CSS color format conversion for web dev
“I have the hex color #ff6347 and need its HSL and RGB CSS strings so I can use them directly in my stylesheet — can you convert it?”
Accessibility luminance check
“What's the relative luminance of the hex color #3a7bd5? I need it to check contrast ratios for accessibility compliance.”
Print design CMYK breakdown
“I'm preparing artwork for print and need the CMYK values for the brand color #0047AB — can you convert that hex code for me?”
Technical details
Endpoint
GEThttps://color-design.x402tookit.com/color-convert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, multi-format color space conversion from a hex code — especially when you need relative luminance (for WCAG contrast calculations), CSS-ready strings, or all major color spaces (RGB, HSL, HSV, CMYK) in a single call. Prefer this over manual calculation or generic utilities when accuracy and completeness across all color models is required.
Side effects
- Invalid or malformed hex color string returns an error or null values
- Missing required 'color' query parameter causes a 400-level error
- Hex values outside standard range may return degraded results indicated by the 'degraded' field
