Chroma.js is a tiny small-ish zero-dependency JavaScript library (13.5kB) for all kinds of color conversions and color scales. Revived with new features and maintained.
Install from npm
npm install chroma-js
Import package into project
import chroma from "chroma-js";Initiate and manipulate colors:
chroma('#D4F880').darken().hex(); // #a1c550Working 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.
You can use it in node.js, too!
npm install chroma-js
Or you can use it in SASS using chromatic-sass!
First clone the repository and install the dev dependencies:
git clone [email protected]:regorxxx/chroma.js.git
cd chroma.js
npm install
Then compile the coffee-script source files to the build files:
npm run build
Don't forget to tests your changes! You will probably also want to add new test to the /test folder in case you added a feature.
npm test
And to update the documentation just run
npm run docs
To preview the docs locally you can use
npm run docs-preview

There have been no commits in X weeks. Is the original repo of chroma.js dead?
Yes! That's why it has been forked and now maintained here.
