If you have wheels and future mods mapped out, or a style you are going for, color choices should be a bit easier.
I personally like the panda look, taken from the Initial D AE86, so if you plan on using any CF parts, a lighter color car will stand out with the contrast more.
I personally think contrasting elements look better on a light base color rather than dark base (black car with white lip kit, white gt wing will look weird compared to a white car with black accents etc.).
Now if you want to "murder out" your car, then black is the only way to go.
White/Black contrast can be played out, but it is hard to F it up if you are not good at color coordinating. Here is my Panda work in progress, white/black contrast with CF/Brushed black metal/Matte black.
