Buy RS3 Green dye
Green dye is a small bottle of dye in RuneScape 3. Players use it to change the color of items in the game. It is made by mixing blue dye and yellow dye. Both of those dyes come from Aggie, the dye maker in Draynor. It can also be bought from the Seamstress in Lletya for 6 coins if you have started Mourning's End Part I or Prisoner of Glouphrie.
Use green dye on a cape to make a green cape. This gives 2.5 Crafting experience. Members who finish the Enlightened Journey quest can use it on an origami balloon to make a green balloon. It also dyes a small rune pouch or a large rune pouch green.
Green dye mixes with other dyes too. Mix it with red dye to make brown dye or Christmas dye. It can also color items like goblin mail, ogre bellows, the Essence of Finality amulet, and Pernix's quiver.
Green dye is not members-only and is not a quest item. It is tradeable, noteable, and can be disassembled. It weighs 0.02 kg, so it is light and easy to carry.
