Laurel Lance and John Diggle will rock new looks in the final season of Arrow.

On Twitter, executive producer Marc Guggenheim shared concept art of the new costumes. Spartan's color motif swaps red for green, likely in honor of Green Arrow, who retired from vigilante life in the Season 7 finale. Aside from the color change, though, his costume remains largely the same.

Laurel's costume, on the other hand, is very different. In honor of her new hero status, she dons a Black Canary costume. She will maintain the overall black color scheme, but she has ditched Black Siren's long black coat. Now, her costume has yellow accents and piping, solidifying her new Canary identity. The suit's pants also have sections that resemble fishnets; this is clearly a callback to the comic book version of the character, who famously wears fishnet stockings with her costume.

Though the Black Canary concept confirms Laurel will assume the moniker, Spartan's concept art bears no label. As such, it is unclear if Diggle will keep his Spartan codename or assume the Green Arrow mantle. Both pieces of concept art appear below.

The costume reveals also put another Arrow mystery to rest. Earlier this month, Guggenheim teased Season 8 with two photos that contained extreme closeups of new costumes. The new concept art proves those costumes belong to Spartan and Black Canary. Per the label on Canary's costume, Brie Thorpe designed it, while Keith Lau created the concept.

Returning Tuesday, October 15 at 9 p.m. ET/PT on The CW, Arrow stars Stephen Amell as Oliver Queen, David Ramsey as John Diggle, Rick Gonzalez as Wild Dog, Juliana Harkavy as Black Canary, Katie Cassidy as Black Siren, Katherine McNamara as Mia Smoak, Joseph David-Jones as Connor Hawke and Ben Lewis as William Clayton-Queen.
