if your pool water is clear and the walls and floor are not slimy, then it is probably not algae. I think most skimmers get discolored after awhile. Probably from a combination of things like body oil, sunscreen, etc.
One other thing --- we NEVER suggest using a copper algaecide. Contrary to popular belief, it is not chlorine that causes blonde hair to turn green, it is copper. The only algaecide we ever recommend using is 60% Polyquat.
