Sorted by caste:
Everyone is Blue
- Arthur's father is on the ruling council of Anitam - chosen because it's patrilineal. Arthur is a perfectly happy blue, and it's actually where I'd place him by personality. Later, of course, he ends up on the ruling council himself. If we're going with everyone-is-blue, he has a voting majority with Merlin and another friend.
- Cat in this scenario is Arthur's legitimate offspring in a patrilineal country like Anitam. He's a less-extreme version of Afen in terms of his relationship with both the caste system and his parents. However, he stays blue out of duty. This version of Cat is probably a Leo-cluster.
- Raven is Arthur's daughter in this scenario. She does not like being a blue. She pulls an Afen - dyes her hair and sneaks into university - and tries to persuade Cat to come with her; he refuses out of a sense of duty. Her mother was blue.
- Merlin is a diplomat and later runs for office alongside Arthur, acting as a counterbalance to his wilder ideas. (I can't see a blue Merlin not having a blue Arthur.) He's not that much older, but feels a lot more mature. This is one of the few ways to get a married Merlin, I think, although I have no idea who he'd marry.
- Drake objects to being blue.
- Darcy does not object very strenuously to being blue. He starts as a pawn in the game blues play, and ends up being quite good at it. He dates Cat at some point probably in the everyone-is-blue scenario.
- Katherine is very stressed because of her pushy parents and basically shrinks into an unhappy Stepford Wife.
- Z as a blue is involved in government or law, and also owns a significant amount of property. He's male in Anitam or female in Voa or Tapa. Either way, Hawk is one of his sons.
- Fox is Irresponsible Heiress. She marries young and rich, and is probably happiest in a matrilineal society where she's allowed to marry some rich purple. In the everyone-is-Anitami-blue scenario, she marries Hawk.
- Hawk is Z's son. May or may not have siblings. Marries or has an ill-advised affair with Fox, depending on her caste and the rules around inheritance.
- Spider are perfectly happy as blues and run exactly as normal: F doing the diplomacy and A running everything behind the scenes. They're like Aitim if you split the people skills and the It-Will-Be-Done into two people. F is probably the one who runs for public office although A is eyeing Avalor's role speculatively.
- Wolf is a rebellious blue, probably Arthur's son. Runs away to join the army at least once. Don't ask where he got the grey hair dye. Don't try to take it away from him; he will growl at you. And possibly bite you.
Everyone is Green
- Arthur Does Not Want to be green. He'll settle for being an actor, with a preference for anything in which he gets to use a sword. He does most of his own stunts, especially swordfighting.
- Cat is an artist or a singer. He's happy. (His paintings sell quite well, as do his albums. He's not at Makel level but, really, who is?) This is one of the glasses-wearing Cats, although if he goes for acting he switches to colour contacts.
- Raven is a happy happy scientist. Which science, you ask? All of them. All of them is the answer. (Raven is a born green if anyone is.)
- Merlin is a contented university lecturer. Green is actually one of the places he fits really well, along with orange.
- Drake is grumpy about it but is settling for being an actor as long as they can get roles playing both genders.
- Darcy is a chemist or physicist or computer programmer. This is fine with him. Green is where he fits by personality. (Amentan Darcy is one of the ones who wears glasses.)
- Katherine goes for doctor if that's green or...somehow ends up as a singer if not?
- Z is either a biologist working on life extension OR a physicist working on FTL.
- Fox as a green will settle for acting. She still marries Hawk, who is a green or a blue probably.
- Hawk as a green has to actually study and get a job. (The horror!) He is the Most Pretentious about whatever it is he studies. Actually, he's probably the eternal student.
- Spider...A is a researcher or computer programmer of some kind, F is maybe an actor or a professor.
- Wolf is literally Telkam. Complete with dyeing his hair and running away to join the army unless someone manages to redirect him into martial arts as a hobby.
Everyone is Yellow
- Arthur as a yellow...probably goes into law? He is quietly dissatisfied but can't quite put his finger on why.
- Cat as a yellow spends most of his time utterly bored. He gets...a job, I guess, because it's expected of him. This is probably one of the Cats who gets snatched up by Z if the Z in question is green or yellow.
- Raven is a journalist who is continually annoyed at being denied higher education. She spends all her disposable income on nonfiction books and academic treatises.
- Merlin...works out the highest-impact career he can have and does that? Probably became a lawyer? If not, he's going for architect.
- Drake is So. Bored. Of this quiz.
- Darcy works as a computer programmer because this is yellow for some reason and it's as close to being green as he can get. Yellow!Darcy, like green!Darcy, wears glasses.
- Katherine is a quiet, dutiful secretary. Probably works for Z.
- Z is a lawyer, and a damn good one too. Where "good" means "persuasive, and also wealthy".
- Fox becomes a trophy wife to some rich yellow or purple.
- Hawk is perfectly happy as a pencil-pusher, to be honest.
- Spider do their usual tricks; A has a desk job that gets her access to computers; F has a public-interface job of some sort.
- Wolf is Running. Away. To. Join. The. Army.
Everyone is Grey
- Arthur rises up the ranks to become a general, or as high as one can get without being blue. He commands armies, but doesn't get to decide where they march. He's happy, mostly.
- Cat as a grey gravitates towards dance and stunt work. Anything that'll get him on stage or screen. He hits the out-of-caste income cap playing background greys in TV shows.
- Raven becomes a police officer and wrangles her way into doing detective work.
- Merlin is a sports coach of some kind. Template attractors say swimming but interpersonal template attractors are saying dance so he can end up tutoring Cat.
- Drake finally found a caste that doesn't suck. Drake is in the army and does well there.
- Darcy also joins the army and turns out to be decent at it. He gets recruited by Spider at some point probably.
- Katherine becomes a dancer.
- Z absolutely refuses to join the army. He joins the police instead and works his way to the top.
- Fox is a sex worker in countries where that's a grey job, and a dancer the rest of the time.
- Hawk joins the police and somehow, by magic (Z), never gets even a reprimand for beating up reds.
- Spider do their usual tricks, potentially involving the secret service. I can't remember whether that was a grey thing or not.
- Wolf has found his calling. He joins the army and is a very enthusiastic soldier. He refuses any promotion that would take him away from the front lines.
Everyone is Orange
- Arthur teaches grey school and eventually gets written up for verbal abuse after he makes one kid cry.
- Cat is an arts or humanities teacher and enjoys it. He probably teaches greens, and might be at the same school as Darcy, in which case there's a betting pool on when they'll start dating.
- Raven gets as much education as she can justify and then teaches green school at the highest level she can get. She forces herself to get over her fear of public speaking, but avoids anything that would make her responsible for small children. She's not the best at teaching but her students admire her passion for the subject.
- Merlin is a primary or middle school teacher and loves it.
- Drake is Bored. Of. This. Quiz. The only thing that appeals is being a social worker the reds might actually approve of, because Drake just wants to burn the entire caste system to the ground at this point. That or sex worker.
- Darcy teaches computer science to greens. He might be at the same school as Cat, in which case there's a betting pool on when they'll start dating. In fact, there are two betting pools: one among the staff and one among the students.
- Katherine is a doctor if that's orange or a nurse if not.
- Z is a doctor if that's orange or a middle school or high school teacher if not. He somehow manages to avoid getting caught having a relationship with one of his students. Even though it happens multiple times.
- Fox is a sex worker if that's orange or a daycare worker if not.
- Hawk objects to being around children or reds or sick people, ew. Radiology tech is about the only orange profession he can stand.
- Spider object to being orange. Fine, F can be a red liason. A is going "ew no talking to people" and probably does something vaguely tech-y in a hospital.
- Wolf...you know the drill.
Everyone is Purple
- Arthur probably runs a horse farm or something.
- Cat is expected to inherit the farm and is so. Bored. If he gets his choice of purple jobs, he probably goes into retail on the customer service side or something.
- Raven wants to start her own business.
- Merlin is an architect if possible or otherwise starts up a building firm and angles for as much creative freedom as possible.
- Drake works on a farm.
- Darcy works for Spider as an engineer or an electrician.
- Katherine is the daughter of someone involved in cloth manufacturing. She probably gets cleaning or housekeeping work, given free choice, or something working in a hospital or nursing home.
- Z runs a business. What does it do? Who knows. Where does his money come from? Don't ask.
- Fox marries the heir to a business. (Spoiler alert: it's Hawk.)
- Hawk is set to inherit his parent's business and therefore does as little as he can get away with.
- Spider start a business together and end up at the head of a corporate empire.
- Wolf does manual labour and finds the most physically demanding jobs he can get without being grey.
Everyone is Red
- Arthur joins riots. He starts riots. He attempts to start a revolution. He's dead before reaching Amentan 7, and his odds of surviving to 6 are low.
- Cat is a trainee teacher. This is probably one of the Cats who gets snatched up by Z somehow, possibly post-decontamination and possibly through extra-legal shenanigans involving adoption and falsification of paperwork. The Z is probably green but might actually also be red. The touch-starvation is what gets him.
- Raven is a coroner and does autopsy demonstrations in which she spends all day every day being horribly jealous of the greens on the other side of the glass.
- Merlin is a teacher at red school who tries to stay out of trouble. He's horribly touch-starved and blames that for the crush he gets on one of his trainees...
- Drake starts riots and torches blue!Z's place.
- Darcy is an engineer/tinker/ etc.
- Katherine is a red doctor and gets over her squeamishness very fast. This is one of the more mature Katherines.
- Z does not come in red, I don't think. If he does, he freaks the heck out and goes, if possible, even more self-loathing than demon!Z. This does not end well either for him or for anyone around him. The theory goes that, if he's already as disgusting as he can possibly get, it doesn't actually matter if he's immoral in other ways. His self-preservation instinct co-operates with social consensus about pollution to mean he only targets reds.
- Fox is a prostitute who will also do hugs.
- Hawk, like Z, doesn't really want to come in red and hates himself if he does. Unlike Z, his self-destructiveness turns inwards instead of outwards. He either commits suicide before he's Amentan-five or finds Fox and falls madly in love with her.
- Spider are running their neighbourhood under the noses of the social workers, and possibly also coordinating riots. Or, attempting to.
- Wolf joins every riot ever, and probably doesn't survive to age 5 (Amentan years). Has even odds of dying before he's 4.
