I don't know if it would help here, but I'm in another hobby, model railroading, and alot of the manufacturers have been switching from bulbs to LED's for headlights. When they first did it, they were using those white ones that looked blue when lit, which really looks unrealistic. One of the solutions is to dip the white ones in Tamiya Clear Orange paint (Tamiya is the brand). It made them look more yellowish, which, while still not correct, looked alot better than the blueish white. They do make other clear colors, so you may be able to experiment with them and possibly come up with a specific color combination you're looking for.
