I have a CM storm Trigger with blue Cherry MX, it's a good keyboard that I got a few years ago and still works perfectly. My only problem is with the backlighting, since my setup is now mostly white/black/wood and the red is not looking good.
I'd like to switch to white LED backlighting, I thought I could buy a pack of white 3mm LEDs and solder them in place of the red ones. I'm concerned about forward voltages, red diodes are usually ~2V and white ones are ~3V.
Many thanks.

You are right about diode forward voltage. There are three common ways to drive the diodes:
Overall, I recommend opening up a keyboard and looking at the design. If you see a small IC with inductor next to it, let me know the part number.
