WandaVision: Why Does Tommy Wear Blue-Green And Why Does Billy Wear Red?

Contains spoilers for WandaVision

In WandaVision's newest episode, everything is starting to fall apart for Wanda (Elizabeth Olsen) as S.W.O.R.D. closes in on Westview and Vision (Paul Bettany) begins to question the universe he lives in. The story inside Westview continues on from the birth of Wanda and Vision's twins, Tommy and Billy, in episode 3. As the family goes through their daily routine in a new '80s setting, the twins start growing up right in front of our eyes, jumping from newborns to five-year-olds, and later to ten-year-olds. With every time jump, the show transitions to a new set of actors portraying Tommy and Billy, with the episode including both Gavin Borders and Jett Klyne playing Tommy, and Baylen Bielitz and Julian Hilliard playing Billy. Thankfully, there is one point of continuity that helps viewers consistently tell the pair apart as they age — their wardrobe. 

While this episode lets fans see Wanda with curly hair and overalls, Vision in a boxy suit, and the neighbor Agnes (Kathryn Hahn) in classic '80s aerobics attire, the twins wear relatively normal clothes. But throughout any wardrobe changes, the show keeps the color spectrum for each character the same. For Tommy, his clothing is always in shades of green and blue with white accents, while Billy wears red with black or dark blue details. Some WandaVision fans might be wondering why the show is doing this, but if you take a look at the two characters in the comics and their superhero counterparts, Speed and Wiccan, the answer is quite obvious.

WandaVision uses the twins' comic book superhero uniforms as inspiration

Just like with all the other details of WandaVision, there's a lot of thought put into what Billy and Tommy wear, and with good reason. While the color-coding in the Marvel TV series is a clever way to make it easy for viewers to tell the two boys apart, it's also an obvious callback to the characters' comic book origins. For Tommy, his blue-green clothing connects with Speed's uniform in the Young Avengers comics. Speed wears an outfit that's entirely dark green with white stripes running up the sides, and WandaVision echoes this in the boy's green, blue, and white striped shirt in this episode. In the comics, the stripes match perfectly with the character's white hair, a trait likely inherited from his uncle, Quicksilver.

For Billy, his look comprises of a black suit with dark blue and silver accents and a bright red cape fashioned at his neck, which matches perfectly with Billy's striped shirt in episode 5. Billy's look in the comics changes a bit over time, but the stark red cape is always a part of the outfit — a clear connection to his mother's iconic uniform. Fans will get a better look at a comic book-accurate Scarlet Witch outfit in next week's WandaVision episode, which looks like it will feature Halloween. If we're lucky, we might see Billy and Tommy suiting up as well.
