How this service works
Parse any CSS color and return it as hex, rgb, hsl, hwb, lab, lch and oklch.
Output
The endpoint returns the input color expressed in multiple CSS color formats (such as hex, RGB, HSL, and named color if applicable), allowing the caller to use whichever representation suits their target environment.
Example use cases
Design token format normalization
“I have a color defined as hsl(204 70% 53%) in our design system — can you convert it to hex so I can use it in our Android app?”
Named color to hex for email template
“What's the hex code for the CSS named color 'cornflowerblue'? I need to hardcode it in an HTML email.”
Hex to RGB for canvas drawing
“Convert #3498db to its RGB values so I can use them in a JavaScript canvas drawing call.”
