I understand that the bat logo on his chest is like a sigil, I understand that the yellow oval is to draw gunfire to the chest which is the only bullet proof part of his costume, I understand the purpose of the cape and cowl is to make him look like a bat and I understand that choice of black and grey as they make it easier to hide in shadows, what I don’t understand is the colour blue! Why does a guy who sneaks around in the night wear blue, and in some comics the blue is actually quite bright almost a sea green turquoise.

So why this strange choice of colour?

    The night sky is blue. But there are preciously few stories where the yellow oval is the bullet proof part of the costume; either the costume is all bullet proof, or not at all.

  • @MrLister I was reading a Cracked article the other night that said much the same thing about how real ninjas would never wear black, because it stands out against the night. And yes, blue was the color they actually wore when trying to be stealthy in the shadows. Jun 22, 2014 at 12:26
  • I also read that cracked article about ninjas wearing dark blue instead of black and a few of my friends and I decided to put it to the test; on a moonlit night both blue and black are visible and on a moonless night neither are visible, but black always tends to blend into the shadows better under any circumstances.

  • Does he wear blue? I always assumed (outside of the bright-blue kids' versions, which are bright-blue because they're kids' versions) that those blue streaks were just the illustrator's way of showing the sheen on a black object.

In universe :

As you can see from the 1948 Batman #47 (Origin of the Batman), Batman wanted to create a suit that would "strike terror into criminals". He deliberately crafted an outfit in the style of a bat, decked out in a mixture of dark colours (blacks, purples and blues) that he feels will make him appear to be a "creature of the night".

His existing clothing in the previous panel consists of a black/blue jacket and dark trousers so these may be colours that he already favours.

enter image description here

A near-identical origin story is seen in the earlier Detective Comics 033 - 1939 albeit with Bruce Wayne wearing a different outfit when he sees the bat. In that case, the bat itself is shaded in blue and grey...

The best explanations I've seen are that printing conventions (not to mention technology) in the earliest days of the Batman comics favoured the sparing use of black ink. Blue was used to create the impression of darkness without having to actually use fill colours. It was also used to highlight black areas where grey would look out of place.

You'll also note that those serials that are intended for younger audiences often favour a bluer palette whereas those that are for older audiences are literally darker with Batman in black.

As you can see from the (huge) diagram below, Batman's suit has changed colour dramatically over the intervening years but almost always with an emphasis on blue for the comics and black for the films where high-contrast materials work better.

Although it may be a total coincidence, the original dictionary that inspired the design of the Batman outfit was itself bound in heavy blue with yellow stripes.

    Yes I've seen that chart and I understand about the limitations of printing technology especially in years past but what I mean was is there a reason why he wears blue within the context of the story.

    @happy-birthday-roberto Given that blue was and is often used to signify black, i.e. persons with black hair has blue in their hair. like this picture of bruce wayne: i18.photobucket.com/albums/b130/SurfNaked788/DC%20Comics/… Maybe within the context of the story the suit is meant to be black and not blue?

  • Hmmm, so you're saying it was never blue it was black and just appeared blue from the reader's point of view, that makes sense, now to just find some confirmation within one of the seventy years worth of stories (good luck to me)!

  • @HappyBirthdayRoboto - It's definitely blue. You see him holding the material in several frames.

As it turn out a blue sheen on a black surface is meant to represent a glossy black surface in DC Comics (and possibly other comics) for example Superman's hair. As the years passed and printing technology improved this look was kept perhaps because it had become traditional.

In old school Batman comics Batman's cape and cowl also had a similar blue sheen which indicated that they were black within the context of the story even though they appeared blue from the point of view of the reader.

The blue sheen look was made by colouring the majority of the area in with black ink leaving only the highlights uncoloured and then the colourist would eventually go over these areas with blue.

As the years passed for one reason or another the artists stopped filling in areas of the cape and cowl with black with a small area left to be coloured blue and the majority of the cape became blue, leading to Batman's light blue look from the 1940s to the 1990s.

But even though the cape and cowl appeared blue within the context of the story they were still black. In Batman #445 Alfred confirms that Wayne's costume is black and grey and not blue and grey. An interesting side note is that the yellow oval on Batman's chest was never yellow but was meant to be gold.

Batman's blue cape and cowl are meant to have been black they were just coloured blue with the assumption that the reader would understand they were black.

  • Good answer but it's worth noting that issue #444 is a very long way into the batman mythos

  • About that, Batman 444 is part of DC's post Crisis on Infinite Earth's continuity where Batman wore his blue costume but it doesn't apply to the New 52 continuitybut he's never worn blue in the New 52. It also doesn't apply to the Silver Age or Golden Age continuities but since comics were pretty wacky back then a "logical" explanation is kind of pointless!

Batman himself gives the reason in the new frontier film when Superman asks this question. "Let's just say I wanted to scare criminals, not kids." -Batman This is the reason for the switch from black to blue. Blue is the kid friendly version of the batsuit in most cases.

  • Is that a verbatim quote from the film about his outfit change?

  • Good answer but to be fair the New Frontier is not canon and even if it were it seems like a bit stupid for Batman to intentionally make his costume less frightening and more colourful.
