Manufacturers fit 4300K daylight-white bulbs since they have the highest Lumen rating (as others said) i.e. they are the brightest.
The original HID lamps produce the blue tint when viewed from some angles through use of prism lenses (and not through use of blue bulbs...).
These lenses are quite expensive, and cheap after-market HID kits simply use higher colour temperate bulbs e.g. 6000k or 8000k to produce the blue tint, then up the Watt from 35W to 55W to compensate for the warmer bulbs being darker in comparison to the cooler 4300k bulbs. This is a cheap way of imitating the results of a proper HID lamp.
Why anyone would want to do this to their car is beyond me, but then again I never did quite get the go-faster stripes that were all the rave in the seventies... yet everyone seemed to be fitting them. And I wasn't a Grandpa then so I guess it is nothing to do with age.
