The Sharks use 14 different colors and somehow it works, generally, each and every time. Looking at that fisherman jersey (blue, teal, white, orange, grey + the waves), there's just a lot going on - let alone the mariner thing. Going blue/orange is just going deeper down the ugly.
Further, what is the connection of the aquafresh wave on the bottom of the mariner? It has three 'waves' - just like aquafresh toothpaste logo. What does 3 have anything to do with the Isles? They have '4' on all sorts of things to represent the Cups. The lighthouse has 5 'beams' of light. What does that represent?
Just a big unconnected mess.
