Different Color Uniform Jersey

[stosh]

A1 is warming up with her team and is wearing a distinctively different shade of green jersey than the rest of team A. When questioned, she says she forgot her shirt, and is borrowing a JV shirt until her mother gets there with hers. At the 12:00 minute before game mark, I go to the table and sure enough, she is marked off as a starter.

I tell both coaches that she cannot play with the different shade shirt, but if she needs to be replaced as a starter after the 10:00 minute mark, there is no penalty for that (if the shirt comes before game time, then we are good to go).

I thought I handled it right, neither coach objected, the shirt showed up 3 minutes into the game, she changed in the locker room, her coach called a TO and got her in the game.

Question: Should she have been allowed to play with a noticebaly different shade shirt? Otherwise was this handled correctly?
