To make green dye in Minecraft, you can follow these steps:
- Find a cactus in the desert biome.
- Smelt the cactus block inside a furnace by placing it in the top cell of the furnace.
- Wait for the furnace to finish smelting the cactus block. You should see the flames cooking the block of cactus.
- Collect the green dye from the output cell of the furnace.
Once you have green dye, you can use it to color various items in Minecraft. To do this, combine the green dye with the item you want to color in a crafting table or a furnace. Some items that can be colored with green dye include leather armor, banners, beds, shulker boxes, and wool.
