Why Bulma knew about the blue hair of Mirai Trunks?

[Hit!!]

Eh either way it's stupid. Either an oopsy in dialogue or something nobody would actually buy for a minute. But I like the crazy theory of Bulma can see the future. That's so Bulma.

No it is a recton... Nothing more.

Stupid it is... But damn it is just a color. Same as Vegeta's hair at the beginning of Z/manga was brown

Vegeta only lasted 1 episode with red hair. That's not a valid comparison.

[Puto]

No, it was definitely more than one. He had red hair in his first appearance, and he had red hair in the Arlia episode too. At least.

Blue and purple are the same words in Japanese...

Nope:

青 "Aoi" means blue or bluish black (or green in old japanese).
藍 "Ai" means indigo.
紫 "Murasaki" means purple or violet.


And IYRC the only error is not having Bulma and Trunks with the same hair color. Purple or blue doesn't matter. Just get them the same.

Another inconsistent thing are the skin color's. Goku's skin has been white, tan, or even a dark tan like in GT.

Let's not even get into the major inconsistency with height that has plagued the series for years. Let's face it, when it comes to the minor details, Dragon Ball always seems to make mistakes. Whether its from Toriyama or Toei.

The Arlia episode was filler.

[Grimlock]

And in Dragon Ball Kai, Vegeta's hair is black in his first appearance. That obviously is because Toriyama didn't have in mind that Saiyans hair are black.

Or he didn't give any instructions about to colourists.

The issue is not that Trunks have blue hair. Is that Bulma refer to him as "the blue haired guy", while his son have violet hair and Future Trunks too.
No need for an explanation, there's no theory... It was a narrative mistake.
"The guy have a sword?"
"The guy have a short jacket with CapsuleCorp logo?"
Or she simply LOOK AT HIM and recognize him.
These variations could have spared us for such a bad mistake (and Pilaf telling us "he look like you", while it doesn't at all...).

Its likely not a narrative mistake. Seems to me like they're trying to establish a retcon. Dragon Ball Super is trying to tell us that Mirai Trunks' hair has always been blue.

How could it have been a mistake if there were literal flashbacks of the Android arc shown?

I'm starting to think the blue hair comment was on purpose and Toei is trolling us

[MadSaiyantist]

We're obviously talking about an In-universe explanation.

In universe? I'm telling you, they want us to accept that Trunks' hair has always been blue. Either that or Bulma was somehow able to oversee the Future Timeline (highly unlikely). None of the Z fighters acknowledged it. On the contrary, they said he looks EXACTLY like present Trunks.

[Neo-Makaiōshin]

It´s possible that the hair "color" that we seen in F!Trunks in DBZ and present Trunks in both DBZ & DBS might not look the same from a out of universe perspective but might actually look the same from an in-universe perspective.

Quoting myself cause it seens to have been ignored.

I find that quite odd when they've been showing Future Trunks with purple hair so much, that now all the sudden they retcon that if that's the case? Still it's not that big a deal. It's stupid, but it's a rather innocent crime/possible retcon. Saying Trunks always had blue hair wouldn't really affect continuity anyways.

[Xiao Long Li]

It would bother me less if Present Trunks also had blue hair like he did in the anime concept art (or if they changed Bulma's hair to purple just like it was in the manga). Now we have Present Trunks and Future Trunks having different hair colors despite being the same human being. Gokuu Black and Gokuu honestly need more "differentiation" than the two Trunks, and that differentiation is already taken care of with different attires. Not only do the two Trunks have different attires aside from the boots, Future Trunks is already a grown-ass man while Present Trunks is a pint-sized kid.

I would be equally bothered if they suddenly gave Gokuu green hair to "differentiate" him from Goten and Gohan.

Anyways, nothing is said about Present Trunks having purple hair, so now we're to assume he's the one with the incorrect (anime) color and actually has blue hair.

Blue and purple are the same words in Japanese...

First off, yeah, purple is murasaki in Japanese. Whereas blue and green are aoi and midori.

Furthermore, Bulma doesn't use any of those words when she referenced Future Trunks having blue hair. 「ブルーの髪の色」 She used the English word for "blue".

[Baggie_Saiyan]

I assume Trunks visited Bulma one time see how she is doing etc and told him he dyed his hair blue as a sign of moving forward and leaving all the mess of the androids behind him.

Maybe in the DB world "blue" refers to all hair colors in the blue/purple spectrum. Just like how in real life we use the word red to refer to orange hair.

[DBZAOTA482]

Bulma's anime hair color shouldn't even be blue at all. It's turquoise.

[FortuneSSJ]

The characters are just assuming he always had blue hair, because there's no plot explanation behind it and this recolor seems to be just a Toriyama's whim.
The only way Future Trunks blue hair would be acceptable to me, would be if he stick around in the main time. Since kid Trunks should grow up one day, this would be the easiest way to distinguish both.

But honestly I don't think Future Trunks will stay in the main timeline. I think Future Mai is not dead and she will be a reason to Trunks go back.
