Question about water polo, regarding referees?

Question

I was watching the olympic gold medal match of mens water polo. I turned it on about midgame. I noticed that the referees walk on an elevated platform with a red, yellow and green carpet on it. Can anyone explain what the color zones mean and what the referee being on those zones signifies?

Answer 1

The colors basically mark in meters where you are in the pool and there are certain rules kind of for each color. Red- extends two meters from the goal, a player cannot be inside the red unless the ball is inside the red. The yellow marks the 5 meters, if you are outside the yellow and you get a foul you can shoot the ball. so yea that's all i know, hope i helped (if anything i said just made sense...it's a little confusing to understand)
