Found a bug, I’m using the default color for my castle and sandstone for my fireplaces. Each time I exit then reload the game the fireplaces revert back to the default color. The chimneys and extensions work fine and retain their color.

As a side note mega huge and many thanks for making this mod, it’s awesome. There is an item I would like to see added and that is a pyramidal roof peak for the castle roofs. See pic:
