Sandy/Dirty Bricks

We all know and love the mossy stone bricks/mossy cobblestone. They are very useful for aging buildings and add a nice pop to a lot of builds. However, given the fact that moss doesn't work in every biome (moss has a lot of difficulty growing in dry climates such as deserts and savannahs) I think adding variants of bricks that use sand and/or dirt to age them would work wonders for use in builds. Not only does it make more sense practically, but it's a good expansion on the already existing block pallet.
