Why Bulma knew about the blue hair of Mirai Trunks?

[CrimsonYouth]

That's the question. How Bulma knew about the new hair color of Trunks before seeing him? The last time she saw him, he had the same hair color Kid Trunks currently has (purple), not blue.

I was very surprised, because she said it as if his blue hair was not at all strange to her. The odd thing is that even in the flashbacks of Ep. 47, Trunks has its usual hair color.

Because her hair is blue also, since he is her son, his hair would be blue.

In conclusion, the one with the wrong hair color is kid trunks ^^

Can this nonsensical hair color topic die already?

If there would be an explanation then yes, i guess.

New design. Explained.

[Kouga]

Well, in Z they never explained that.

That's just a plothole, in the flashbacks, Future Trunks's hair was purple.

[Shinomori]

I thought it was kind of weird for Bulma to mention Trunks' hair, and it has nothing to do with her knowing it was blue before she saw him. A lot of people are amazingly wondering if Trunks' hair change will be explained "in show". If that happens, I would think that would be very weird because the simplest explanation should be it was the creators' or animators' choice to make his hair blue. Plain and simple. I would be good with that explanation. Yet if we have some dialogue within the show explaining his hair, that would just be strange in my book and most certainly won't add up with the original DBZ.

Maybe Toriyama forgot that his was purple and nobody at Toei wanted to tell him

[SSJ YUSUKE]

Because he just looks better with blue hair.
It's design choice, a brilliant one.

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

[Pannaliciour]

Maybe just maybe Future Trunks stayed in contact (video-chat or something) with this Bulma until shit when south. But that can't be it because he should know that Goku was alive.

[SaiyaSith]

Probably because Bulma has always thought about what Trunks looked like all grown up. She most likely knows that Trunks hair will turn blue when he gets older. Similar to how when a lot of children with blonde hair grow up and it turns dirty blonde/ brown. Also, with Bulma's technology she probably knows everything about his DNA... lol. Kid Trunks hair is purple so his hair will obviously turn blue one day too. They have identical genetics.

It's called an error. Get used to it, Super is going to be making a lot more as it goes on.

It's not an error. They clearly chose to give him blue hair as an adult.

The error is Bulma shouldn't have any idea he has blue hair. He's had purple hair last time she saw him. She magically knows he has blue hair somehow now, like as if he always had it.

Yeah the only other problem I see besides proof reading your own comment, is how much this one contributes to the topic at hand.
