Making changes in the LobbyPlayer.cs so as to make multiple players choose the same color in the lobby

HI, I've been working on a multiplayer game in which there will be two teams fighting against each other, I have made a hook to the Player so as to get the playerColor from the LobbyPlayer.cs and perform a certain function. But now I'm stuck, I want to make some changes to the LobbyPlayer.cs so as multiple players in the lobby can choose the same color (maximum 5 players). It's very important to do so as the players chosen the same color will belong to the same team. Can someone tell me ?, help!
