Cyan Dye is used to add cyan color to glass, wool, terracotta, concrete powder, banner and shulker box. To make a Cyan Dye you will need Cactus, Lapis Lazuli and Cactus Green Dye. Please follow the following steps to make a Cyan Dye.
In order to make a cyan dye, the basic item you will have to find is cactus. You can find cactus blocks in desert biomes and take at least one block of cactus.
After that you will have to find lapis lazuli gemstone. You need to find and get at least one lapis lazuli stone. Use your iron pickaxe to obtain it.
Cactus Green Dye
After collecting a cactus block, you need to use the furnace to make a cactus green dye. Head towards the furnace and add a cactus block in the upper box and coal in the lower box, you will get a cactus green dye in the right-side box of the furnace. Add this green dye in your “ready to use” stock.
Now move towards the crafting table to craft cyan dye. Add lapis lazuli gemstone and cactus green dye in adjacent cells of any row or column of 3*3 crafting grid. You will get cyan dyes in the right-side box of the crafting table. Bring these into your “ready to use” stock.
