i know you might not have this experience, but....Be careful with paint chips or small samples. The Awlgrip "Flag Blue", for expample is the classic blue you see on Hinckleys, Sabres, and a lot of other boats. But if you look at the paint samples, most people would think it's too dark and would pick a much lighter (or Royal Blue).
I've known a number of people that get into a paint job and only discover they didn't get what they thought it would be from a little chip.
