Spectrum

The No Hassle Colorpicker

See the demo and docs: http://bgrins.github.io/spectrum.

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.

Basic Usage

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>

npm

Spectrum is registered as package with npm. It can be installed with:

npm install spectrum-colorpicker

Bower

Spectrum is registered as a package with Bower, so it can be pulled down using:

bower install spectrum

Building Spectrum Locally

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
