Lighting Ideas/Help

Hey, I'm not sure if this is the right area for this, but i looked and coming here i think will get the job done quicker. I've always been a fan of adding things to my car to make them more unique and personal, but it's always been to a cheap, high mileage car that just gets me from A to B so I never added much to them or spent time planning things. This has changed.
I just purchased a '06 Aerio Manual with only 56,000 miles on it so needless to say I plan on taking greater care of this car and put more into it because of this, and planning better and not skimping out on quality of parts.
It's white exterior with a black with silver accent interior and red dash lights (not sure if they all are red or not) and I wanted to add some interior neon lights under the seats and dashboard. The problem is I don't really want to use red lights because to me thats just too much red. Since you guy's have an idea on what the inside looks like, what color do you think would go good with the red dash. The only colors i wanna stay away from are red and green, other than that its fair game for colors. Any ideas will be helpful because I'm just getting an idea on what to do and I don't really have an eye for color combinations.
