I think if u have 6k+ HID's I think that yellow gives more of a JDM contrast, 6k might look cleaner, but it's pretty common

to quote myself from another thread:
as you can see from the posted pic, even the stock 2is color temperature of 4300k does not put out as much useable light as 3000k.
to sum up, 3000k for maximum useable light, 4300k to match oem 2is HID's, 6000k for (imo) the best color/light mix.
anything after that, and it's pure aesthetics.
just an FYI...
myth: the higher the "k", the brigher the bulb/HID kit.
fact: the higher the "k", the less useable light output.
fyi, the "k" is a measurement of color temperature in degrees kelvin that determines the hue (read: gradation/variety of a color) of the light source.

as you move along the "k" scale curve from left to right, you'll see that there is an increase in light output, peaking somewhere between 2000k and 2500k. personally, i don't know why manufacturers don't use that color temperature, but from an aesthetic point of view i'm glad they didn't... but i digress.
the stock 4300k for the oem D4S bulbs for the 2is is right on the border between white and yellow, but has more light output than most popular D4S bulb temperatures (6000k/8000k/10,000k). however, for aesthetic's sake, the 4300 still has a hint of yellow, so you'll have to go with a higher color temperature to get that white/blue-ish tint. and of the popular D4S bulb temperatures, 6000k has the most optimal mix of color and useable light.
in short, i agree w/ L-S-D: for the best color/useable light mix, i'd go with 6000k.

6000k has LESS useable light .... (visible light gets less as temp(k) goes higher)

It's XenonDepot's graph, hence the watermark. I'm sure a lot of you guys have, but if you want even more info, that this sit doesn't provide, click the link in my sig.
Cheers!

anyone have the 3000k fog hid kit? does the output looks deep yellow or is it light yellow? Mine has a very light yellow color output to it. I don't have the vinyl yellow on the fog lens overlay. Do you guys know if i put it on the output of the hid will be more yellow? Thanks

also, so everyone knows, CL also has a lighting section:

i personally chose 6000k for my HID fog kit, only to have that color/light output mix. i just hope four_o_two doesn't think my 6000k HID fogs are crayon-colored lights.

Whoa this is nice, almost like a science project. Thanks for the graph of color output! 
Most of the post in the Lighting thread mainly for look questions, not much about visibility or fogy questions.
Thanks again for confirming the 3k!
Happy Holiday!!
