Actually, with high cya levels, the higher chlorine levels are no more likely to fade things than the lower chlorine/lower cya levels are. And, one other thing. You shouldn't smell chlorine in your pool. If you do, it usually means you need more chlorine! Sounds crazy, I know, but usually when you smell chlorine it means you have a CC reading and need to shock your pool to get rid of it. A properly maintained pool should not have a noticeable chlorine smell.
