Chroma.js
Chroma.js is a JavaScript library for working with colors in visualizations. In contrast to many similar libraries it supports advanced color models like CIE Lab and Hue-Chroma-Lightness which are helpful to overcome the traps of equidistant HSV colors. Also it includes support for color scales and the beautiful palettes by Cynthia Brewer.
To analyze the different color models you also build an interactive color selector around Chroma.js. There's a nice fork of this picker that let's you easily export the colors: hcl-picker.
