What Items do you wish would be Dyeable?

[MsQi]

I would like the current dye system to be improved and allow for two-tone dyeing. The UI seems to reflect that this might have been a Thing (why else would there be two dye slots if only one dye is ever used) but it has never been implemented.

Where is this?

EDIT: Ok I think I know what you mean. Those are for purchased dyes that are also obtainable in game. Two different items are sources for the same color. Though I would love to see a two or three dye system I don't think it is currently set up for it. Each item needs multiple slots.
