How don you dye a stuff in RuneScape

Idk who cares about runescape world of warcraft is where its at. I disagree, and i have only figured out how to dye goblin mails. U have to get a dye, right click and click "use" the click on the mail (al done in ur inventory). U will need to do this to complete a member quest, i forget which one. I also can't remember if dying is just member stuff and for that i am sorry. Sicerely, Astro Z11
