Nice implementation. I spent a lot of time looking at these when I was putting together a UI that needed some color picking. When I read the headline, I thought you may have made something like my "dropper"-style color picker using canvas: http://github.com/sstrudeau/jquery-dropper http://github.com/sstrudeau/jquery-dropper Mine allows you to pick a color from an image. Two big caveats (haven't found workarounds for): < IE9 doesn't work and the excanvas VML hack doesn't help (no pixel-level access to images); and images loaded into a canvas element have a same-origin restriction similar to XHR.
