I like a clean white light. I think the higher 10k blue would make things harder to see at night.
Also something I read from a HID company
"10000K Xenon HID lights produce white-blue light with a touch of purple hue to it. 10000K is probably as high as you want to go for a street car, both to stay legal and to have any kind of visibility on the road. At these high color temperatures light output is significantly reduced, especially during rain or fog. Higher color temperature lights appear brighter when looking directly at them, but they how lower light output as far as the drivers visibility goes. 10000K Xenon lights have approximately 2300 lumens of light."
"6000K Xenon HID bulbs give off a very attractive white light with a touch of blue/purple hue to it. This is my favorite color temperature as far as Xenon headlights go. They have just the right combination of blue/purple hue, which attracts attention, but go overboard where they become annoying to oncoming traffic. I use this in my headlights and would never go back to stock Xenon bulbs, these look very nice. 6000K Xenon HID lights produce approximately 2900 lumens, much higher than regular halogen bulbs."
