Advanced javaScript color picker and color conversion / calculation (rgb, hsv, hsl, hex, cmyk, cmy, XYZ, Lab, alpha, WCAG 2.0, ...)
This script should not be not be installed directly. It is a library for other scripts to include with the meta directive // @require https://update.greasyfork.org/scripts/23181/147862/colorPicker.js
An advanced, fast and small (45.4KB, 19.5KB gZip) JavaScript (framework independent) color picker (color chooser) that uses only one javaScript (x.min.js) file, so no extra HTML, CSS, images, etc... on IE9+ and internet browsers.
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) 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. colors.js can convert 182 different combinations of color spaces (rgb2HSV, RGB2hsl, rgb2RGB, HEX2Lab, ...)
