API overview

Go here to take a look at the complete API.

Color formats

Different color formats are supported: hex, rgb, rgba, hsl, hsla and cmyk.


A valid hex color can be:

  • #rrggbb[aa](6/8-digit, long form)
  • #rgb[a] (3/4-digit, short form) with r, g, b, a in [0-9a-fA-F].


A valid rgb color is an object like this {r, g, b} with r, b, g numeric values in [0, 255].


A valid rgba color is an object like this {r, g, b, a} with r, g, b numeric values in [0, 255] and a in [0, 1].


A valid hsl color is an object like this {h, s, l} with:

  • h (hue): [0-359]°
  • s (saturation): [0-100]%
  • l (lightness): [0-100]%.


A valid hsl color is an object like this {h, s, l} with:

  • h (hue): [0-359]°
  • s (saturation): [0-100]%
  • l (lightness): [0-100]%
  • a (alpha): [0-1].


A valid cmyk color is an object like this {c, m, y, k} with c, m, y, k numeric values in [0, 100].


You can convert a color in any format to any other supported format.

Specific functions by color format

Then there are more specific color format functions. You can also convert a Color to a redeable string format or a CSS string format. Go here to take a look at the complete API.
