What Legacy chest to use Black/Black dye on?

While creating new characters before server merges, I finally got myself a Black/Black dye from one of the Cantina crates. Now the question is, what Legacy chest piece better to use it on?

I have practially every Legacy chest piece there is: Alliance Special crates, Legacy vendors, DVL rewards, you name it. But since it's a one-time opportunity, I want to make sure I use the dye on the one that really looks cool with it. Any suggestions?
