You asked a loaded question..As we all know, we all have different opinions and are entitled to them. Sometimes asking a question like this can confuse you even more. Been there done that!! We all like input though.
I think as Frank said. Reds & blues will always be safe colors. Kind of like TT wheels. You see them everywhere but always look good & excepted. Me personally I like being different. I think green in the right hue would look good. I think if the car is built & detailed right, you can almost pull off any color. I have seen some cars with what you would think is an hideious color, but they were able to pull it off. But some...you say WTF?? Once again though just my opinion.
In the long run though, it's your car. Do what you think looks best.
Did I confuse you more??
