Why do some of the humans' hair colors change? Do they dye it or did something with the ectobiology change?
Is the troll blood color change because of something different with the ectobiology, or is it a troll biology headcanon that their environment can affect their physical development? Like how some reptiles develop as male or female based on temperature and not genetics, or something like the Kyre from Cassiopeia Quinn (https://www.cassiopeiaquinn.com/comic/xeno-log-002, https://www.cassiopeiaquinn.com/comic/alium), where young trolls absorb DNA from being around their lusus and develop to match them? Or is it just standard bloodswap logic where there doesn't need to be a reason for, it's just an AU.
Hey there, thanks for the big ask! Hope you don't mind a big answer, because it's me again.
ALTERFALL is an AU, and we don't try to adhere it to any sort of continuity with Homestuck proper, like something like - say - the Crow Strider AU does. There's no in-universe diegetic reason why the AF session didn't turn out like canon Homestuck, it wasn't Rose getting the ectobiology wrong or anything like that; but the ectobiology *is* different, which is why everyone's genetics are different from canon. For example, Jade and Dirk are actually related via ectobiology here, rather than Jade being related to John/Jake/Jane and only being a Strider via adoption. This was the inspiration for making Dirk's hair black and so on (so to answer your question, it isn't dyed!). If we left it alone, every pairing of human would be in some way related either through blood or adoption, and that would make it weird when Rose and Jade kiss.
That's right. It was all for yuri. Our dark agenda is revealed.
In any case, we didn't actually decide on all of these elements (changing blood colours, changing genetics for the humans, that including changing hair colours etc.) all at once, and it wasn't all just for the sake of it being an AU. If anyone's interested in a bit of production history, take a peek under the cut.
