I own an 85 TA, T-tpos, 305, TPI. The car has the silver or grey ground effects. I guess the previous owner took out the sticker that has the info on it since I tore that car apart looking for it in all the places the dealer said it should be. The car itself is a blue color, not too dark.

Put in your year and make and you will get a pretty good chart on colors for that year.

I had heard of this site before but Drew put me in touch with it yesterday and I thought their color charts were pretty helpful.
