I wanted a colorpicker that didn't require images, and that had an API that made sense to me as a developer who has worked with color in a number of applications. I had tried a number of existing plugins, but decided to try and make a smaller, simpler one.
I started using canvas, then switched to CSS gradients, since it turned out to be easier to manage, and provided better cross browser support.
Head over to the docs for more information. There is a visual demo of the different options hosted at: http://bgrins.github.io/spectrum.
<script src='spectrum.js'></script>
<link rel='stylesheet' href='spectrum.css' />
<input id='colorpicker' />
<script>
$("#colorpicker").spectrum({
color: "#f00"
});
</script>
Spectrum is registered as a jQuery plugin on the jQuery plugin repository here: http://plugins.jquery.com/spectrum/
Visit https://travis-ci.org/bgrins/spectrum to view the status of the automated tests.
If you'd like to download and use the plugin, head over to http://bgrins.github.io/spectrum/ and click the 'Download Zip' button.
If you'd like to run the development version, spectrum uses Grunt to automate the testing, linting, and building. Head over to http://gruntjs.com/getting-started for more information. First, clone the repository, then run:
npm install -g grunt-cli
npm install
# runs jshint and the unit test suite
grunt
# runs jshint, the unit test suite, and builds a minified version of the file.
grunt build
