Remarkable Hexweave Essence

Added in 10.0.5, this is an optional reagent for Draenor Tailoring Hexweave armor that alters the appearance of the Hexweave armor pieces to a black appearance instead of the default red color. Once crafted, the pieces will say "Remarkable" under the name of the item in the item description. Aside from being an additional transmogrification option, there appears to be no other added benefit.

Thank you! As a tailor obsessed with creating transmogs for myself, I wanted to create all the sets but lost track of which essence created which recolor. Your comment was the only reference I could find on Wowhead.
