One of my engineers had a bug up his rumpus about the color of the power button light on some rackmount gear at the studio (I forget what it was). His solution was to ask his artist wife which color mixed with the offending color would give him a pleasing blue. After some head scratching and rummaging around an art supply store, they found some transparent tape of the right shade. He cut a piece to fit over the button and I'll be damned if it didn't work.
Granted, I don't think I could muster the energy to "fix" something (at least in my eyes) so trivial, but you might want to try that low tech solution and see if it works. You could always make the button a completely "lights out" affair without a whole lot of fuss.
Cheers,
