What do you mean no buttons? I'm all for color-coding and a remote control, but that is in addition to the touch-screen interface. Are you saying all your skin screens are static images and you can't actually click any of the buttons?
BTW: I really do like color-coding, but maybe you should just change the text color and keep the button a brushed aluminum or gun-metal. There is way to much bright color in those screen-shots.
