Why are you so insistent that no focus be taken away from the game? Would a few players having differently-colored sticks or a little patch on their uniform really take your attention from the game?

Like, they're not out there doing a Broadway on ice performance, they're just putting some tape on sticks. The game doesn't change because of some tape. If you have trouble focusing on the game because the rainbow tape is distracting, that's probably a you issue. If you don't like what you see on your screen, you can either ignore it, or change the channel. Easy as that.
