I ran an assembly line, (20+ years ago, and not for autos, granted) and the pieces came to the line and painting was done in batches before the line. I'm not sure how or why one would want to paint random colors, but, maybe shit is like the jetsons now, I really don't know. It seems onerous without a cost savings. I'm not trying to argue a point, I'm just saying I'm not seeing many red frames chosen, and traditionally, thats an issue. Also, if differing frame colors didn't have some sort of additional work, the cost seems a little out of wack.
