Since a couple of other mods add sand of different colors, it would be good if these mods would unite around a common tagging scheme for these and use the tags in all relevant recipes. This would allow people to use the Black Sand added by Terrestria to build the Black Sandstone added by BYG, for example.

My suggestion is to add the item tags c:pink_sand, c:black_sand, etc, and update all recipes to use that tag instead of the specific items.
