I would have to completely agree with you Sir Nelson. When I see a Tan castle I instantly think it is in a desert somewhere. Unlike when I see a Bley castle and think that it is a representation of a stone structure, somewhere in Europe (where there aren’t too many deserts).
I personally would pick to build a castle out of Bley (and I do), rather than tan.
