I was looking at doing this, too. The problem with the powermate is actually getting the thing open. I'm sure changing the color can't be that hard once you get the case open... anybody had any luck with this?
once you pull that rubber off of the bottom, the led's are right there. That should do the trick for ya. But I don't know how you are going to go from red to blue. It uses the same leds for the lighting. You would have to alter the chip or soemthing on it.

I see, all I had to do was find a screw driver small enough to fit between without scratching the visible metal. The red to blue would be easy to do, but hard to fit it in such a small space... I would think it would be possible to find a small inverter chip and maybe fit that in there.
They are surface mounted LEDs... meaning they are VERY small and hard to soldier. Also, I don't even have any LEDs small enough to replace them at the moment. I can unscrew the rotational sensor and almost get it out, but the USB connection seems to be holding it in, and from what I can see can't be disconnected easilly. It looks like there might be space for a inverter on the other side... anybody else tried this?
jacob: FYI, theh powermates START blue, and it hink the goal is to make them a different color I doubt that it uses optical tracking to sense the rotation of the knob, too
And you wouldn't change a chip, you'd just swap the LED
