1.8 and previous versions:
This mod makes chain, iron, gold, and diamond armor able to be dyed. To change the color of a piece of armor, just place the piece and the dye of your choice in the crafting table. All of the dyes in the game work. Different types of base armor(Chain, Iron, Gold, Diamond) create different variations of the colors so even more customization is available. Sponges are also now able to be crafted and used to clean the dyes from the armor. All recipes are shapeless. Dyed armor has its own creative tab now to cut down on clutter.
Dye your chain,iron,gold,diamond like you would leather. Colors as of right now don't show on the icon but show when worn.
To remove dye from your armor use a bucket of water in the crafting grid with the armor you choose.
To craft chainmail first make the links using iron nuggets in the following pattern and then use the standard crafting layouts for armor with the links as the material.
