Why i can't have blond hair when i can have all other colours of the rainbow?

In lore reasons stat the blond hair recessive gene is gone from the human race at this point.

What about the Steiner family then?

Um, concerning the whole recessive gene thing, I'm pretty sure blue hair isn't genetic. At all. Unless there was some unfortunate relations with a carebear or treasure troll that I was unaware of.

Blonde hair dye is also apparently Lostech? Haha!

Ummm, no. That's not how the genes that determine hair color work. Hair color genes are epistatic - meaning it is determined by multiple genes interacting with each other. The only way for blonde hair to not exist is for all hair color to be black - any other color carries genes for blonde hair. In fact black haired people may still carry blonde hair genes.

It goes in the other direction as well - the only way to not have black hair is for everyone to be blonde. Still no guarantee even in that case either.

I had blond hair when I was a child by the time I was in my teens it had gone a dark brown and now it's starting to grey :P

Victor Davion also haad blonde hair aaand he was only half Steiner.

Family background will determine which chracter pictures are available. You can customize them to some degree.

That whole bit about Blonde Hair being recessive is from a poorly informed BBC article from 16 years ago, which was proto-fake-internet-news apparently, at the time.

Also, I'm pretty sure the lore, since the 80s, has had blondes. This argument keeps cropping up as defense from people who seem like they've never actually been exposed to Battletech before. Kinda odd. Granted I haven't delved into this game but have observed from a distance, just seems bizarre.

Seriously, go read the old books on the Wolf's Dragoons or others--the fiction and what-not. Blondes abound, Clanners and Inner Sphere alike, high-borns and average mech-jockeys and below. Honestly the Houses and their backgrounds were largely a patistiche/palette drawn from broad Western/.European, Indian, and Chinese/Japanese/Broadly Pacific Asian civilizations and the peoples within them were largely implied to reflect that, at least according to the compendium I have sitting on my shelf. Not like you had monolithic bodies of people but there was a fair bit of consistency among them, again, going off the ficiton. You could find pretty much anyone of "stereotypical" historical and cultural backgrounds, like all the other games FASA put out at the time. Kinda like how you could have a German netrunner working with a full-blooded Sioux warrior in Shadowrun, for example. Nobody was really left out--incidentally, including blondes.

Their explanation is inconsistent and nonsensical in the context, and seems driven by other factors, but I deign to suggest what that might be, because I really don't know.

It is fiction, guys. If the author wants all blonds or no blonds then that's just how they wrote it.

Maybe this will be a feature in some future dlc?

Yeah, how about citing some of that "lore"?
The real answer: devs are bigoted against blondes.

everyone in the future has way better taste in hair color

i can back this up w/ lore
