If a game is started before I have joined, I can still join after the fact, but will be kicked out when the participating players are finished. No idea what happens if I submit a color before i'm kicked out, but it probably still wouldn't take me into account.
Thanks for the feedback and the suggestion. Now when joining after the game started, the player is told that she/he a spectator and cannot input a color code
