I'm driving my RGB LEDs with two shift registers (74HC595) from an Arduino Uno. After playing with some potentiometers, I found the following resistor values to offer the best color balance and highest contrast: Red: 430-Ohm, Green: 910-Ohm, Blue: 750-Ohm
Another tip that would have helped me: These LEDs are the "clear" variety (meaning they have a spotlight effect.) Sparkfun also sells "diffused" RGB LEDs. These LEDs have a much softer glow.

I suggest you purchase "diffused" RGB LEDs for this pad. The "clear" ones leave too much of a spot. I wish I would have known that. :-/
