I have a lighted keyboard, but its because I type in the dark alot, and in addition my last keyboard had no lights and the letters painted on and i used it until the letters faded and it was sometimes a guessing game for what letter i needed. 
But my keyboard isn't one of those multi-coloured rainbow things. Its just red. And its either red or not red ♥
We specifically sought out the red one because blue light gives me migraines.

Otherwise its boring. 

My mouse is fancy-ish, though. Its got a few extra buttons, and I can customize its inner glow light. That I find to be pointless. You never see it once you're using the mouse. 

also uh shit its almost may.
