I've had similar thoughts, but if you look at your controls, you will there there are some other issues to work around. Some of them have a small dot that lights up - so you'd need to somehow mask that off when painting those controls (or paint over it an live without the little lighted dot). On the temp controls, the center dot is lighted, then red dots for warm and blue for cool - again, more masking, or you'd need to paint the dots back in, or put stickers in them.
