My initial assassin armor was purple, but then I bought new armor and bought purple dye and remover to make it a soft pink and nothing happened. The only color that actually changed the top and bottom of the armor was silver and that made it a dull gray. Are we ever going to be able to change the color of Assassin armor because right now I am seeing hundreds of identical blues.
Not sure why the dye remover didn't work; perhaps try it with blue or red and dye remover instead of purple?
