Chroma.js is a tiny JavaScript library (12kB) for all kinds of color conversions and color scales.
Initiate and manipulate colors:
chroma('#D4F880').darken().hex(); // #9BC04BWorking with color scales is easy, too:
scale = chroma.scale(['white', 'red']);
scale(0.5).hex(); // #FF7F7FLab/Lch interpolation looks better than RGB
chroma.scale(['white', 'red']).mode('lab');Custom domains! Quantiles! Color Brewer!!
chroma.scale('RdYlBu').domain(myValues, 7, 'quantiles');And why not use logarithmic color scales once in your life?
chroma.scale(['lightyellow', 'navy']).domain([1, 100000], 7, 'log');Please check the most current documentation here:
or here, for the interactive version:
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
To compile the coffee-script source files you have to run (might have to ``npm install` first)
grunt
To run the tests simply run
npm test
