There are other mods that add colored sands and recipes that use them, so it would be good if these mods could agree on a common way of handling these. I would suggest c:black_sand as an item tag to use on terrestria:basalt_sand so that mods like "Biomes You'll Go", which contain a craftable Black Sandstone can update their recipes to use the item tag c:black_sand instead of their item byg:black_sand.
