+/* 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.
