LOL Prob'ly not ;0) People who build custom bikes are every bit as fussy as we are about their finished product. Don't take it (customer wanting black) as a slag on your work guy cuz a) your work is fantastic :0) and it's just a bike thing. LOL
I'm pretty big about subtle whenever I do anything to my bike. IE: you'll never see any of those LED's glowing under my gas tank. I will likely do a custom paint job on the bike down the road and it will incorporate the ever overdone flames in the design. However, they will be very light and subtle ghost flames. Only someone taking a real close look and appreciating the work will actually see them - like the prize at the bottom of the Cracker Jack box ;0) It's just a personal thing and yes it plays down the art of a job but those who take the time to look closer will "get it" :0)
That said, I'm looking forrward to being good enough at this to be able to pull off the antiquing finishes and burnished look, but for now bike stuff will likely all be done black cuz it hides my booboos ;0) and is easier to maintain with all of the weather and oil/grease etc that bikes are prone to come in contact with ;0)
Beauty seat! :0)
