Q: If there is more than one color in a system at Catastrophe levels, can a player trigger the Catastrophe for only one of them?

A: The situation whereby there might be two colors meeting the criteria for a Catastrophe is highly theoretical. It’s just not something which happens under normal circumstances. However, should such a situation arise, we would rule that someone can trigger a Catastrophe on just one of the colors if desired. Of course the other color is still… a Catastrophe waiting to happen…
