About
The Color API takes a hex color code and returns everything about it: its name (like "Cruise" or "Tango"), RGB, HSL, CMYK, and HSV values, the closest matching named color, and even an image of the swatch. It's completely free with no key, making it perfect for design tools, brand guides, or any app that works with colors.
