EIC Privateer

Thanks for taking the time to read and any help is very much appreciated.

Does anyone know how to use "false colours" in-game in EIC: Privateer? I played the game for a while but i haven't been able to figure it out and google searching has yielded very little results for this game.

Anyway if anyone knows or could provide me with a link to somewhere that explains how it works i'd be very gratefull.

Regards
