I don't understand this, unless it means that the tile colour must follow the
same progression (from what's already in the hex) as a regular tile lay.
This is a good general rule, but we need to be able to declare exceptions in
a game definition.

If this is true, I would think it would solve the Pfalz problem (just notice
that the hex is already yellow).
