Just buy 4300, or 5000k bulbs from a GOOD brand name. No egay crap. And the color should be good. 6000 if you like a blueish tint, but that's where
I have 6000k on my 240sx. I haven't stood in front of it with the HID's on in a while but if I remember right they look white, no tint of blue whatsoever. I could be wrong though I'll check when it gets a little darker.
