PHP код:

new TeamColor[9];
format(TeamColor, sizeof TeamColor, "{ff0000}"); // Team color here, I put RED just for example
public OnPlayerText(playerid, text[])
{
    if(IsPlayerAdmin(playerid))
    {
     new pName[MAX_PLAYER_NAME], String[128], Prefix[] = "{FF0000}[Admin] ";
        GetPlayerName(playerid, pName, 24);
        format(String, sizeof(String), "%s%s%s %s", Prefix, pName, TeamColor, text);
        SendClientMessageToAll(-1,String);
        return 1;
    }
    return 1;
} 


Define a global variable, in this case TeamColor, use it to save team colors for cases like this.
