It totally depends on the lens to be honest.
My LEDs are 6300K and have turned out a little bluer than I would have hoped. I had 6000K HIDs in my Focus too and that was a little bluer than anticipated also.
In a decent OEM projector lens I do not know how blue it is going to look. In my experience 6000K HID bulbs never produce a white a light as you would want.
I have had an OEM S2000 behind me and the 4300Ks are piercing white (and damn bright) and not yellow at all.
