Forge: Team Colors

Why is it, is the red and blue teams colors are “attackers” and “defenders” rather than “red” and “blue”? wouldn’t it have been easier and less confusing to do that?
As well as the other teams being their designated color, rather than 3, 4, 5, 6, 7, 8?

I didn’t figure that part out was until I messed around with it on Initial spawns, and respawns
