HTML5 color eyedropper

This is an uber-simple html5 eye dropper tool that creates a json array of rgba values. It’s the format I like to use for my demos and while I have a few colorpickers installed in my browsers there wasn’t one that let me pick a bunch of colors quickly from one image and get them in the format I needed. With some quick hacking I was able to put this together in about 50 lines of Javascript. Hopefully this leads to some more color full demos in the future.
