I have aftermarket HID lighting in my car and truck. One set is 4300k and the other is 6000k. Both sets of bulbs are clear in appearance. But the 6000k has a blue tinge and the 4300k is bright white. I will have to do some research on how they get the light spectrum to change without changing the UV shield color.
