[Tournaments SoD + FreshMod] Hard Bots Tournament / Prize 10 000р

Choosing a castle and color: trading first for the castle, and then for the color.
!!! If identical cities appear, a new pair of castles is generated.

!!! If the pair of castles is not satisfactory, each player can regenerate a new pair of castles once for 500 gold (paid to the opponent), with the option to ban any castle before generation (so that it does not appear). The red player decides first whether the pair is acceptable or not.

Can the trading for the color happen first, before generating the pair of castles, or does the trading for the right to choose the castle first happen even before generating the pair?
