v1.5

This is a jQuery plugin that creates a colour picker from an input field. It is a fork of another plugin with many modifications made to make it more suited to integrate with Shiny and to add some useful features.

Modifications by Dean Attali:

• Added "limited" palette that allows the user to specify their only a set of allowed colour rather than any colour
• Added "allowTransparent" setting which allows users to check a checkbox to select the colour "transparent"
• Added "showColour" setting which determines if to show the selected colour as the text, as the background colour of the input field, or both
• Added "returnName" setting which makes the widget return a name instead of HEX value when possible
• Added "closeOnClick" settings which closes the selection panel after a colour has been selected
• Removed many unnecessary features
• Removed dependency on images and made the colour picker completely CSS

Additional modifications by David Griswold:

• Added "allowAlpha" option that allows the user to select colours with an alpha transparency channel
• Made inputs more flexible by allowing colours to be entered as names or as hex, rgb, rgba, hsl, or hsla strings

This plugin works for IE8+, Chrome, Firefox, mobile, and should work for all other major browsers.

Modified plugin is being used in colourpicker - an R package providing colour pickers for Shiny apps.

The index.html page contains very basic examples of how to use this plugin.
