As far as dying glamour, you can EITHER dye the item whose appearance you are going to be using before glamouring it, OR glamour it over the item you will be wearing and THEN dye it. Dyes placed on the worn item will be removed when glamouring over it.

For the Monk AF, I can't check right now, but from memory I'd guess honey yellow? Or maybe coeurl? Try putting on a piece of the gear you want to match, and then try the different shades of yellow on the piece you're going to be dying until it looks right to you.

It's a shame, but a lot of the more unique pieces are just slightly off from our current dye options, so you can't match them just right.
