1. Rules do not cover the color of the shorts. They all could wear different colors and not be illegal.
2. I would tell the player to "stop it" but only make it an issue if it literally delayed the team from getting the ball.
3. Don't worry about it, I just tell them to move back quietly if it is the first time I see it is close.
Peace
