Chroma.js

Chroma.js is a tiny JavaScript library (12kB) for all kinds of color conversions and color scales.

Initiate and manipulate colors:

``javascript
chroma('#D4F880').darken().hex(); // #9BC04B
`

Working with color scales is easy, too:

`javascript
scale = chroma.scale(['white', 'red']);
scale(0.5).hex(); // #FF7F7F
`

Lab/Lch interpolation looks better than RGB

`javascript
chroma.scale(['white', 'red']).mode('lab');
`

Custom domains! Quantiles! Color Brewer!!

`javascript
chroma.scale('RdYlBu').domain(myValues, 7, 'quantiles');
`

And why not use logarithmic color scales once in your life?

`javascript
chroma.scale(['lightyellow', 'navy']).domain([1, 100000], 7, 'log');
`

Why not dive into the interactive API docs (there's a static version, too) and download chroma.min.js right away.

You can use it in node.js, too!

npm install chroma-js
