Sorry for being a HID noob but got 2 questions. 1. Is 4300k meant to have a tint of blue in it? 2. Is it normal for the HID lights to turn blue at startup and turn warmer (whiter) over time while running?

Interesting how you say you take a photo of it, they come out yellow, but look blue in person. I find it the other way around.
Anyways, firstly it is right for them to start off a different colour to what they look like warmed up. It's the result of the salts in it heating up and becoming a gas. If you have ever turned on those large warehouse lights that start really dim, you get the idea.
As for the colour, the optic quality of the lens has part in this as well. If...

the lens is not of high optic quality, the light from the source can "split" so to speak meaning that the final output isn't a clean combination of all the wavelenghts of light so that instead of a pure white colour, you start to see the other components of it. Part of this is also emphasised more because of the fact your projectors weren't made for HID and the light source of the lamp may not sit in the focal point of the lens like the original bulb did.
