Personally, none. I can't say I'm a fan of the Color DMD. It's great that it's available for people that want it, but personally I find the colors washed out and they don't add much to experience. In most instances the varying shades of orange used in the traditional DMDs accentuate the images and animation more naturally and that detail is lost with the Color DMD.
