Do they have a 2 tone Fire Red Pearl and Vivid Black? I've seen that on a FLHTC and a FLHTCUI and it is a gorgeous combination. Otherwise, go with your gut feeling on the solid color........I like 'em both.
I hate black............it looks great when it's clean, but keeping it clean is a real pain in the a$$. It shows the small scratches more then any other color, and it shows the dust and dirt more then any other color.
Red, white, even silver are much better colors to maintain.
I wanted black, but my wife felt that she would be wearing black and it would not accesorize well-she chose Brandy-wine-it works! Thought I was on top of the heap until I saw my first Black Pearl-that's a fine lookin bike,why don't they call it grey?
