The jQuery Color GitHub Library is being used on 21,000+ websites.

jQuery Color is a plugin for the jQuery JavaScript framework, which adds a simple animation API to jQuery. For example, it will allow developers to parse string color values like #abcdef, rgb(100, 200, 255), rgba(100, 200, 255, 0.5), red and other common color values.

The goal is to make it simpler to use color values that are common in CSS, with JavaScript. It also gives the ability to define color properties like saturation, hue and others.

It was built by the team behind jQuery, which lends itself to believe that it will be supported well into the future.
