 # colorPicker and colors
 
-An advanced, fast but small **javaScript** (only, framework independent) **color picker** (or color chooser for desktop use) that uses only one javaScript (.js) file (no extra HTML, CSS, images, etc... on IE9+ and internet browsers).<br />ColorPicker works in all browsers incl. IE6+ (an extra CSS has to be made to make it work in IE6 though and some additional setTimeout tricks to make it work in IE5.5)<br />

 **colorPicker.js** uses **colors.js**, a small but comprehensive tool for color conversions / calculations (WCAG 2.0, contrast, color difference, layer mix, etc.)... 
 
 With **colors.js** (~8.7k or way smaller if other color spaces and complex calculations are taken out...) you can also build your own simpler and / or smaller color pickers quite easy as demonstrated on the [demo page](http://dematte.at/cpn).<br />
