Chroma.js is a tiny JavaScript library (14kB) 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');Why not dive into the interactive documentation (there's a static version, too). You can download chroma.min.js or use the hosted version on cdnjs.com.
You can use it in node.js, too!
npm install chroma-js
Or you can use it in SASS using chromatic-sass!
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
And to update the documentation (thanks!), just do
npm install --global markdown-to-html http-server
cd docs/
make && make preview

There have been no commits in X weeks. Is chroma.js dead?
No! It's just that the author of this library has other things to do than devoting every week of his life to making cosmetic changes to a piece of software that is working just fine as it is, just so that people like you don't feel like it's abandoned and left alone in this world to die. Bugs will be fixed. Some new things will come at some point. Patience.
