When to use this API

Convert brand colors into all required formats for CSS custom properties (HSL), JavaScript constants (HEX), and native mobile code (RGB).

Convert colors to RGB to compute relative luminance and WCAG contrast ratios for accessibility compliance checks.

Can I input an RGB string like rgb(62, 201, 151)?

Yes. The API accepts HEX strings (#3EC997), CSS RGB strings (rgb(62, 201, 151)), and HSL strings (hsl(158, 56%, 52%)).

Does the API support alpha/transparency?

Currently, the API handles opaque colors. RGBA and HSLA support is not available.

Is the HEX output uppercase or lowercase?

The HEX value is returned in uppercase (e.g., #3EC997).

Can I convert named CSS colors like "coral"?

No. Pass the explicit HEX, RGB, or HSL value. Use a CSS color name reference to find the corresponding hex code.
