Low bloods with nearly all my headcanons on display!! Sollux probably has too much drip so probably out of character traits too..

The midbloods are next!!

Intro to Alternian Biology: respiratory pigments

Like the blood of most species on Earth and Alternia, trolls' blood derives its color from metalloproteins used to transport oxygen. Unlike most species on Earth and Alternia, troll blood contains multiple types of oxygen-transport proteins--five in total.

HEMERYTHRIN is the primary oxygen-transport protein in the blood of seadwelling trolls, and is also present in significant concentrations in purplebloods. It is violet-pink when oxygenated. Much Alternian sea life uses hemerythrin as its sole or primary oxygen transport protein, as do many Earth marine invertebrates.

HEMOCYANIN is the primary oxygen-transport protein of landdwelling highbloods (blue and purple) and present in significant concentrations down to olive. It is dark blue when oxygenated. Hemocyanin is also found in the blood of many Earth mollusks and arthropods.

CHLOROCRUORIN is present in very small quantities across the hemospectrum, and in high concentrations in greenbloods; it was the primary blood pigment in limebloods, which are now extinct. Chlorocruorin is a dichromatic compound which appears light green in dilute solutions, including normal blood, and red when highly concentrated; an uncommon mutation causing extreme overproduction of chlorocruorin thus results in bright red blood. On Earth, chlorocruorin is mostly found in worms.

COBOGLOBIN is an important oxygen-transport protein in low and midblood trolls and is most highly concentrated in goldbloods, the only caste for which it is primary, with significant concentrations occurring in every hemotype from rust to teal. It is yellow-orange in color when deoxygenated. Coboglobin is the only Alternian blood protein that does not occur in Earth biology.

HEMOGLOBIN is the primary oxygen-transport protein in rustblooded trolls. The highest concentrations occur in burgundy bloods, and it is present in significant quantities in all blood castes up to olive. Fuschiabloods also have hemoglobin in relatively small but still significant quantities, notably more than in any of the other high blood castes. It is dark red when oxygenated. Nearly all Earth vertebrate species rely on hemoglobin for oxygen transport.

Additional notes:

The gray color of trolls' skin comes from black eumelanin and blue-gray carotenoproteins in the skin cells, the concentration of which increases with age. The yellow color of trolls' irises comes from yellow carotenoproteins. These are present in most troll tissues, but their color is usually masked by the darker skin pigments or the more vivid blood pigments. They do, however, contribute to the color of yellow blood, the only hemotype dominated by a transport protein which is colorless when oxygenated.

High concentrations of chlorocruorin are correlated with conciliatory impulses. Sopor slime is a highly oxygenated fluid containing significant concentrations of chlorocruorin, which give it its green color and are believed by many to contribute to its dampening effect on sleep rage and daymares, though the mechanism is not known. No surviving castes have as much as 50% chlorocruorin, while the now-extinct lime bloods had just over. Trolls with the rare cherry red mutation, however, have over 90% chlorocruorin, twice as concentrated as any other surviving caste.

It has been theorized that the cherry red mutation is a throwback to a now-extinct subspecies of troll which relied solely on chlorocrourin for oxygen transport. There were many subspecies in Alternia's evolutionary past, some more successful and widespread than others. In prehistory it is thought that none used more than one oxygen transport protein, as is typical in most planetary ecologies including Earth's. However, early hybrids benefited from the adaptive advantages of diversifying oxygen transport, and the mixing of subspecies through kleptogenetic reproductive strategies eventually resulted in the distribution of diverse respiratory pigments seen in the modern hemospectrum.

you are so very homestuck knowledgeable. when you have the time and should inspiration strike, please tell all your headcanons about oliveblood trolls.

ooo what a great question! for this one i think first we'd need to break down current stereotypes about olivebloods. there's actually not much that we're given about them tbh

according to the homestuck wiki, which is based on info from both the comic and more dubiously canon things like friendsim and hiveswap, the olive caste's two singular traits seem to be "wild animal" and "romance liker". both of these, obviously, are traits pulled from our wonderful main girl nepeta, who was the singular representation of the olive caste for a long time; alongside her dancestors. which is quite cute, who doesn't love nepeta?

the thing is though that i am one of those nitpicky people who likes to say, "well, hey now, nepeta isn't actually representative of her caste at ALL." in fact, none of the beta trolls are. i honestly feel like it should be assumed that just like the beta kids, the beta trolls are weirdos, and not really the 'norm' in their society.

nepeta lives out in the wilderness very specifically away from society in a way that is remarked on as being unusual even for someone of her color; and she does not even understand what role her caste would have given her in normal society. and i mean... considering aradia tavros and sollux are LOWER than nepeta, it doesn't really make sense for them all to have nicer houses than her unless she's unusual in her situation.

^ nepeta is in fact NOT a good representation of olivebloods.

which means... no, i don't think all olive trolls are romance obsessed wilderness girls, actually, sorry, hiveswap friendsim, i have to shelve you from my alternia analysis for now.

luckily, there ARE other olivebloods in the series!

first of all, the other leijons. unfortunately, none of them are really "good" examples either. meulin is from an entirely different planet, and disciple is from an ancient history perhaps even less representative of "normal" life than nepeta is. all we really get from them is stuff we already knew from nepeta-- the wildness, the relationship interest. with an added fact that both meulins seem to be somewhat bookish.

and so who does that bring us to? the final canonical oliveblood.

that's right.

troll will smith.

troll will smith is canonically an oliveblood. not only that, but he's a famous actor, which means he is basically a "model" for society- for what it looks like once you "have it all made". i would imagine this goes even more for alternia, supposedly a very movie-geared society.

the two troll will smith features that canonically exist on alternia are Fresh Prince and Hitch. in both of these films, will smith plays a character that is self-made and clever, a regular guy who is just skilled. it should also be noted that while a "threshecutioner" is a job with a heavy blueblood populous, greenbloods can also be one, and it's common enough that a show about it wasn't cut by the alternian dictatorship.

so therefore, what traits can we pull that all of these olivebloods (and equius lol) display to us?

olive trolls are lower class, but they're capable of working up through their connections

likely due to this, olive trolls are often clever and self made. they're likely quick-witted and sharp

they're good at their jobs! most olive trolls that are seen in the comic are very good with their respective practices (be it drawing, writing, bookkeeping, or melee fighting)

it's possible that olive trolls have a good intuition, and are fairly in touch with their own instincts. this would explain why some of them seem to fare better in the wild or in fights, and also why they are stereotyped as having a natural inclination for relationships. i think this is also a good transition ground between the impressive physical psionics of the castes lower than olive, and the emotional/mental psionics of the highbloods above them.

so, there we go. these are my olive headcanons! they're not comfortably well off or anything, but they're not wild animals either-- they're hard workers and skilled at what they put their minds to. probably usually working a nine to five and doing their best in life hoping to move up with a good quadrant or promotion. at least, in my headcanon anyway- no need to take this as fact!

troll oc dump!!!

[approximateknowledge]

tumblr: hemotype yourself

i have no illusions this will be even vaguely a plausible spread but im doing it anyways

[rrottinggutzz]

divider dump bc why not (TW: blood)

i made these!

NF2U without credits more under the cut >vv<

i would add more but i cant.

[ithinkdogshouldvote2]

I didnt. Dndads hiveswap au be upon ye

algebralternian trolls

another bfdi x homestuck crossover decided to give these guys some blood in their lives

[zombiespiderz]

Trollkin Flag, for homestuck troll fictionkin!! This doesn't have to be for just troll characters, it can be for the troll species in general! ::::)

One of the weakest Homestuck criticisms I see pop up every now and then is that the Hemoloyalty system is bad because “it’s not a clear-cut metaphor for any one specific real-world bigotry.” Acting as if it is a poorly made example of Sci-Fi/Fantasy Racism since it’s used to cover and express Racism, Classism, Xenophobia, Misogyny, etc.

It always makes me wonder if they’re new to fiction that contains Fantasy Racism, because Fantasy Racism systems covering multiple bigotries is entirely normal. It’s the standard, even.

You know.

Because that’s how actual real world bigotry operates?

For example… Racism does not stop at a judgment of skin color. It never just affects how your race is perceived and then stops before it dips into any other bigotry. Racism is almost never “Oh, ew, you’re brown,” with no other follow up. It’s a long series of assumptions and judgments made on your (perceived) race. Racism is deeply entangled with- you guessed it!- Classism, Xenophobia, Misogyny, all kinds of things.

Classic examples of Racism include:

Having your expressions of femininity and womanhood denied or fetishized based on your race, which happens quite regularly to Black and East Asian women in particular,

Suspicions towards Black people in middle class-rich suburban neighborhoods/gated communities, based on the assumption that “they could never legitimately afford to live there” so they “must be trespassing and/or a criminal”,

… And nutjobs screaming at people who are Latino or Arabic, or they perceive as Latino or Arabic, to “go back to their country” whether or not they were actually born there.

Are these all derived from Racism? Yes! But are they also combining forces with a different bigotry to help strengthen that racism? Yes! This is how it works! Fantasy Racism often has their fictional bigotry cast a wide net of judgments and assumptions that wind up making it all look very messy and unclear and containing multiple bigotries because that’s how it works in real life! You cannot in earnest say that a fictionalized bigotry system is bad because it “isn’t one clear cut thing” without looking like a moron. Are you sheltered? Have you only put one lone dying brain cell into this? Have you never experienced bigotry before, or thought about how it operates? I fear that you may need to do some reflecting!
