The way i look at paint decision, you first have to decide what impression you want the bike to give. in other word, choose a theme, old school. similar to stock, wild.. then post a picture of your bike with your parameter, color preferences.. something will pop up.
if you choose a theme or personality to the bike, different colors will probably fit, and you will like them because it says what you want it to say. so, you wont be disapointed of your decision
someone mention mustang light green, it would look in the theme of CHIPPY's bike, which is one i love because of the vintage look, and he keep a color that no one else would have kept, and it look really good.
