Minecraft wiki entry for Dye, associated text: Dyes are a set of 16 items used to change the color of wool, terracotta, certain mobs, the patterns on banners, shulker boxes, glass, concrete powder, candles, beds, firework stars, and text on signs. In Bedrock Edition they can also be used to dye water in a cauldron (which is thereafter used to dye leather armor); in Java Edition leather armor can be dyed directly. In Education Edition dyes can also be used to dye balloons and glow sticks.
