Hmm...
I've done some coloring so far, but not much.
This one is weird. When I tried to dye my Felt Coif of Toiling to Grey, I get offered to make:
Felt coif of Toiling (Grey)
and
Felt Coif of Casting (Grey)

Is it just in case player made the mistake so they can change during coloring?
I didn't received this offer for my Felt Robe of Casting...
