I'm looking for a keyboard that has either blue or custom backlighting on it that also uses the same MX Blues that the BWU uses. My budget is $150 but less is always better. I have a blue setup going right now and the green lighting on the new Black Widow Ultimate is stuck on green. I know that the old generation had blue lighting but would I be sacrificing some key features by buying that model?
Look up Ducky Shine keyboards. You can get them in any config you want (tenkey section or not, keyswitches, backlight colour etc). They are kinda expensive but some of the best out there.
