On a side note, I ended up thinking up of a couple of names for each of the other teams that could reference to colors (even though we don't need the color naming rule).

Team 1 - SQFD - Squid - Squids can change color to camouflage themselves, so yeah.

Team 3 - BARX (I would of gone with BRAX, but nah) - Bark - The bark of trees are brown, not a lot to explain here.

Team 4 - GVML - Gamble - Gambling makes me thing of money and money is green, so there's that.

How do they sound? Thought of them at a random time, so yeah.
