When we build CMS, we provide options to users for customizations. We will use all sort of form fields, for example, text input, date picker, drop down list, auto complete, etc... If the CMS offers theme layout customization, it's inevitable to involve color input UI.
Here we have 8 great color pickers for you:
Tiny Colorpicker is a crossbrowser lib that creates a color picker (form) input. Its a easy way to add color pickers to your forms or user interface. It has a unique UI which I think it looks really good. You can set the picker as image and choose the color from the image.
A color picker for Twitter Boostrap. The UI not the best but it has wide range of sliders to create the color you want. It also has Saved Colors feature to reuse previously chosen colors.
Fancy and customizable colorpicker plugin for Twitter Bootstrap. It's quite a comprehensive one with configurable options and plenty of methods and events to create your own color picker.
A simple component to select color in the same way you select color in Adobe Photoshop. Powered by jQuery, it has some useful method and events.
evol-colorpicker is a web color picker which looks like the one in Microsoft Office 2010. It can be used inline or as a popup bound to a text box. It comes with several color palettes, can track selection history and supports "transparent" color. It is a full jQuery UI widget, supporting various configurations and themes.
