Feature originally in Quark - that unfortunately is very unlikely to be ported to Fabric anytime soon
Midori Blocks are a green counterpart to Purpur. These are made with Cactus Green, with the same recipes as the Purpur blocks.
Midori means "green" in Japanese.
A twist: make these blocks to be crafted by "compressing" moss blocks in a similar way than sand to sandstone instead of green dye.
