What it is?
rgbaColorPicker is a color picker, obviously, but what it does that surprising few other don't is allow selection with alpha transparency. Back in 'ye-olde days' web browser didn't support anything more advanced that a solid color, or no color at all (completely transparent in other words) this was to be excepted, but current browsers are a different story. With such a new fangled feature you'd think it'd be more quickly adopted but it really hasn't been, still few sites use alpha colors even though the vase majority of browser support them.
Is it compatible?
Compatible is a relative term, relative to who you care to support, but rgba colors are actually far better supported then you might think. Support for them breaks down like this:
• Firefox 3.0.5
• Safari 3.2.1
• Opera 10.0 beta
• Internet Explorer 9
• Google Chrome 0.4.154.33
• Sunrise 1.7.5
• Stainless 0.2.5
• Flock 1.2.7
• Camino 2.0b1
• Safari Mobile (all versions)
• Android Brwoser (all versions)
• Blackberry Storm Browser (all versions)
Those are just the browsers that can't handle the alpha part of it, all older browsers (with three exceptions listed below) will simple display a solid color instead, so as long as long as you keep that in mind there shouldn't be problems. The few browsers with problems simply don't display any color however, they are:
• Internet Explorer pre 6
• Netscape pre 5
• Seamoney pre 1.2

Anything else i should know?
Perhaps. The script requires jQuery (it is a jQuery plugin after all), if thats not an issue then it's really very easy to set-up, as simple as including a single file if you'd like. If your the kind of person who wants more control then there are options set up for that, either external stylesheets, callback functions, or both if you choose. Full details can be found in the readme.md file.
The plugin was written by me, Phillip Gooch, and makes use of the tinycolor.js library by bgrins, speaking of github, the color picker is up there too, you can view it at the rgbaColorPicker github page, feel free to fork and and play around, if you fix a bug or add a feature send a pull request and I'll get it integrated into the master branch. Ouside of github posts about updates will be made over at my personal blog Fat Folder Design. Finally, if github or blog comments aren't your thing and your having a problem you can always send me a direct email at phillip.gooch@gmail.com
