Let's settle this once and for all.
For all intents and purposes OP's pictures look almost identical to the myriad of images on google's image search with the qeuery "10000k hid" with some variance for improper white balance and different exposure times affecting color and brightness.

I still think that the difference in color output is likely in OP's head but if he's like to come back with a side by side comparison between his car and his friends' cars then perhaps we can extrapolate more information. Otherwise this thread should have run its course long ago....
