As far as I know. Turn signals amber, stop/tail red, headlights white, markers amber. These are standard colors used all over the world, I believe by an international agreement of regulators and manufacturers. They are also required by law. My nieghbor's son just spent $250 to do customizing lights etc.. on his pickup only to be cited Saturday night as they don't meet DOT regulations. He will have to remove them and pay a fine.
Vehicle lighting regulations are very specific as to color, size, intensity and placement.
You can buy all kinds of neat stuff for cars and they will sell it to you but it may not be legal for street use.
My pet peeve is the striped tail light covers with the logos. They cover 50% of the tail/stop lights surface area. Look great in the daytime but very hard to see at night or during reduced visibility.
