LAC: Red paint prone to oxidation?

I always thought the problem was UV rather than oxygen.  Colors at the 
red end of the visible spectrum reflect or reject less UV, so it gets 
absorbed and ages/fades the paint.

The best examples of this I have seen are Budweiser and Pepsi cans left 
outside for a long time - the red will be all gone but the blue will 
still be intact.

But I could be completely wrong...
