You know, when I have to memorize colours for my guy on DEX I just look at all the colours down and remember it as a rant.
cloth 1
cloth 2
leather 1
leather 2
metal 1
metal 2
this is the order it comes in and then I just say, like my mage armour for instance (it's easy to remember and easier then posting sooo much):
red, black, black, black, red, red
simple order there, but it's also easier then posting 6 files
