Steve, that 'old orange' look that you see on shellacked balls is similar to what I often find on old store-bought pool cues, especially the ones that were refinished by amateurs, and most of those were seldom, if ever, exposed to sunlight;i.e-if it's similar stuff, I don't think the darkening of the shellack has much to do with sunlight. As you suggest, it might be something in the shellack (or whatever it really is) that is 'going bad' with age. My guess is that whatever the amateur cue refinishers painted onto the cues is the same stuff that people painted on their baseballs (the ones that went bad, anyway).
