Does the Colour Preferences tab need to be enabled somehow in the .lud to show up in the game player? I looked at a number of games and all I ever saw was the Player and Advanced tabs in the Preferences window.
The colour preferences tab was removed from newer version of Ludii, due to difficulties in maintaining it for all games.
It may still be mentioned in some of our more outdated documentation, I'll try to remove that in the future.
Apologies for any misleading information.
