 was a mixture of offline and online.

-/* Plugin for jQuery for working with colors.
- *
- * Version 1.1.
- *
- * Inspiration from jQuery color animation plugin by John Resig.
- *
- * Released under the MIT license by Ole Laursen, October 2009.
- *
- * Examples:
- *
- *   $.color.parse("#fff").scale('rgb', 0.25).add('a', -0.5).toString()
- *   var c = $.color.extract($("#mydiv"), 'background-color');
- *   console.log(c.r, c.g, c.b, c.a);
- *   $.color.make(100, 50, 25, 0.4).toString() // returns "rgba(100,50,25,0.4)"
- *
- * Note that .scale() and .add() return the same modified object
- * instead of making a new one.
- *
- * V. 1.1: Fix error handling so e.g. parsing an empty string does
- * produce a color rather than just crashing.
