Bug in adding dye to items

i noticed that all of the items such as the robes and gear needs the regular item. example is

Cotton Coif of Casting (Green) needs Cotton Coif of Casting & All-purpose Green Dye

and

Cotton Coif of Toiling (Green) needs Cotton Coif of Toiling & All-purpose Green Dye

the issue i noticed though is there's an error for the felt coif of casting when coloring it.

Felt Coif of Casting (Black) needs Felt Coif of Toiling & All-purpose Black Dye

every item i looked at requires that item to dye, but this one in particular doesn't. i just wanted to point out the oversight to the dev staff so it could get corrected in the future. so far the felt coif of casting is the only item i noticed that has a different item pre dye.
