chroma-elm

A native version of Chroma.js that allows you to: * use W3C X11 color names.
* create color scales, * use different color spaces such as CMYK, HSLA, LAB, LCH and RGB, * modify colors using interpolate, set/get alpha, lighten/darken, saturate/desaturate, * compare colors using WCAG contrast, * use existing color maps such as Brewer, cmocean, Cividis, Turbo, Sinebow, Parula, Virdis, Plasma, Magma and Inferno.

There is an example site showing how to use the library.
