i can get you ANY color HID kit out.. Florida law says that anything other than white for headlights would be illegal. SO, even with 8000k bulbs, it's up to the officer that pulls you over. If THEY think it's "too blue" you will get a citation and the judge will back them up.
But yes, I can get GREEN, ORANGE, PINK, YELLOW, PURPLE, BLUE ect.....
4300k is the most common factory color although many cars have the 5000k or 6000k kits from the factory
