I believe that some gear should not by dyeable. But for the stuff that is they really need to add a Main/sub colour for the dye system, too often have I attempted to dye gear to find I've only died like a 1/4 of the the inside cloth and I'm still wearing a white shirt.

If it's possible within "Memory limitations" I'd love to see the abillity to customize the colour of our crafted gear some more, there is of course a case of going too far... Ultima Online I'm looking at you and your neon colours!
