Shark eyesight depends on the species, but the fast sharks' eyes are contrast sensitive and some have very good vision, hence where you end and something else begins will decide for them whether they will have a crack at something. Yellow fins look like a separate part from you, so a shark may swoop in on your "trailing escorts" and grab one. Many years ago an underwater photographer had an earlier photo shoot in the day where he and others wore silver-painted wetsuits of the smooth neoprene skin type. Later on he had another underwater photographic job where he swapped to a standard black wetsuit jacket, but kept on wearing those silver wetsuit pants. A shark came in and decided to attack the silver "Kingfish" that were either his escort, or his captives, and he got chomped on the legs. There has to be a lesson there! Myself, although one can look like a seal in the wrong locations, my fins are always black as the "Ace of Spades" if I am in hunting locations.
If you want to read up on shark capabilities then find a copy of the "Shark Chronicles" which documents in layman's terms the current factual knowledge concerning all facets of shark physiology and behaviour and is completely devoid of the sensationalist drivel you read in some of the annual "shark scare" media outpourings.
