Why is Spider-Man's suit red and blue?

Spidey's Suit Colors

Here are answers and opinions from FAQ Farmers:

  • That was the color of the spider who bit him in the movie. As far as the comic books go, those were just the colors he chose.
  • Most superhero costumes in the 1960s favored bright primary colors such as red and blue, sometimes with yellow. (Recall Superman, the Flash, Iron Man, Captain America, Captain Marvel, the X-Men, etc.) Exceptions include Green Lantern and Green Arrow. By contrast, villains often sported purple and/or green, along with gray and black. (Dr. Doom, Magneto, Dr. Octopus, the Lizard, Kang, Green Goblin, Luthor-as-supervillain, Impossible Man, etc). Batman stands out as a major exception because he uses the same black/gray motif common among villains, suggesting his "darker" nature compared to other superheroes. Likewise, Marvel broke the four-color barrier by introducing the green Hulk, who always sported purple pants--another departure from the standard superhero motif.
  • Because Superman is red and blue! Spider-Man and Superman are both just average joes behind the super scenes. Marvel used these colors as an allegory to a superhero with similar circumstances.
  • Superman was a DC comic character, and spiderman was Marvel, different comics, also, back when comics where most popular, the creators stressed alot of patriotism in their characters, using red blue and some white
  • Because of Mary-Jane. Her hair is red and her eyes are blue!
  • Because the colors of the American Flag are Red,White and Blue. Spider-mans suit is Red and Blue plus his eyes are White.

Our first comic heroes (and villains) were limited to bright colors because of the cost of black ink. Black ink (even today) cost a great deal more than any other color because it is the most used color for print.

Spider-Man's first appearance shows the costume in the darker blue (not black) with blue highlights, red and the darker-red web design. The only spider of the same color is the Long-jawed Orb Weaver.

I would also imagine they either wanted it to be "kid friendly" like DC did for Robin The Boy Wonder or color was a new thing for these guys who worked in B&W during their early years ... "Hey look, COLORS, wow let's use those!"

peter Parker was brain storming in his room when he decided on it because he likes red and blue

To give Spider-Man a more sinister, dangerous look: Spider-man's original costume was actually RED AND BLACK. Black is often depicted in US super-hero comics as 'Black with blue highlights', which usually gives way to 'blue with black shadows'. This then is mis-intrepretted as blue. From Superman and Wonder Woman's black hair, to The Batman's black cape and Batmobile, to many Marvel and DC heroes and villains who's names begin with "Black". Many have their black costumes (Black Canary, the original X-Men, symbiote costumed Spider-Man, and Venom) depicted as 'black with some blue highlights', but this soon give way to a more commercial, heroic and colorful 'blue'.

Spider-Man's costume has three colours: Red (background for webbed areas), Black (bodysuit, webs & borders on eyes) and mirror/silver for the "2-way mirror" eye lenses. Spider-Man's black body suit has been misrepresented as blue for years (as with the black parts of The Batman's costume for 50 years, until Frank Miller's "The Dark Knight Returns" corrected this) and in recent years even the black borders around Spider-Man's eye lenses have been depicted with blue highlights, which may lead to them also being depicted as blue. The black spider on his chest might also soon be misrepresented with blue highlights, and subsequently misintrepretted as blue. The RED AND BLACK color scheme for Spider-Man's costume was in keeping with the Spider motif: dangerous and sinister, almost appearing villainous. This is why the eyes of Spider-Man's mask are so sinister. The Red and Blue scheme, along with larger, 'distressed, hapless' eyes on the mask are to depict Spider-man as more of a pathetic victim, rather than the sinister Red & Black with ruthless predatory eyes (the perfect counter-balance to Peter Parkers good natured, bookworm personality; and giving him a sleek, daring, edgy, near-sinister evil alter ego that would naturally be desired by someone so straight laced.)
