< p > Looking for mobile first, tiny foot print, fast, scaleable, flexible and pluggable...< br >
This < strong > 4.4KB< / strong > small HSB color picker is based on a subset of < a href = "https://github.com/PitPik/colorPicker/blob/master/colors.js" > colors.js< / a > from it's big brother < a href = "http://dematte.at/colorPicker/" > colorPicker< / a > , supports all modern features like touch and MS pointer, GPU accelerated rendering, battery friendly requestAnimationFrame and provides a lot of hooks for developers to write plugins (See demo plugins below in < a href = "#demo" > Demo< / a > ).< / p >
< a name = "demo" id = "demo" > < / a >
< h2 > Demo< / h2 >
On all inputs with calssName 'color': < pre > $('input.color').colorPicker();< / pre >
< p > Switch between plugins:
< select id = "pluginSelect" >
< option value = "desktop" > Desktop (no plugin)< / option >
< option value = "mobile" > Mobile< / option >
< option value = "input" > Input fields< / option >
< option value = "noalpha" > Default without alpha< / option >
< option value = "small" > Default but smaller< / option >
< / select >
(see index.js for more details...)

< input class = "color" value = "#B6BD79" / >
< input class = "color" value = "rgb(162, 63, 3)" / >
< input class = "color" value = "hsl(32, 95%, 23%)" / >

< p > Tiny jQuery colorPicker only loads if triggered to show. It uses battery saving technologies and super fast rendering for best performance on desktop and mobile browsers.< br >
This colorPicker is very flexible to modify and customize and there is an easy way to write plugins to extend functionality, look and feel...< br >
As Tiny jQuery colorPicker uses < a href = "https://github.com/PitPik/colorPicker/blob/master/colors.js" > colors.js< / a > from it's big brother < a href = "http://dematte.at/colorPicker/" > colorPicker< / a > , it provides a clean and rich color model and API that enables flexible extending for programmers. (See < a href = "https://github.com/PitPik/colorPicker" > colorPicker on GitHub< / a > for more details)< / p >
< p > The following snipped shows how easy it is to make plugins: use for mobile< / p >
