familiar, but less

Anonymous Guest asked:

you say that if there are yinglet questions we can ask you.

okay.

what kinda colour cones thingies do they have

Val's said yinglets have similar color vision systems to humans, so they likely have either the same, or very similar cone cells for their vision. they typically have red, green, and blue, but not UV. however, over any part of the retina in their big eyes, they have less of those cones to work with

their vision can't distinguish different kinds of the same hue as easily, so in a pile of similar hues and shades that many humans would recognize as a dozen, a yinglet might see three or four. they like bold, bright colors typically, and this might be part of why that is

that one shade of blue is a possible exception, but as far as I can tell, that's also a cultural thing, not instinctual; and this one AU sequence with Ran claims in the description that which specific shade of blue might set off that reaction will vary from yinglet to yinglet, though I'd figure the reed itself is the "ground truth" there

I haven't seen many folks play out having this different color vision in character, but maybe some folks would get some positive feels from it. still, obviously, fan yinglets don't need to be stuck to this restriction, whether due to mutations or to being from a separate universe unrelated to the comic's yinglet biology, so don't feel confined, y'all!

Zhis may have ramifications on my job as an art restorer...

If they have a less cone density (but presumably at least as large or greater rod density) compared to humans, would that also mean that in their vision, the colour information has less spatial resolution than brightness? Kind of like chroma subsampling in image compression.

I don't believe the amount of color cones would be reduced to that level; it'd mean having so few that it'd count as a color blindness, instead of just less precise color vision. however, there is a different factor making their detail vision a bit worse, which is that their pupils are huge. their horizontal vision resolution can be very tight, due to the slit pupil shape, but the vertical size makes details fuzzier in the vertical. it doesn't seem to be strong enough to affect reading and writing, though, or I'd expect Kassen to comment on it in comic.

Hmm, interesting, I would have expected a slit aperture to produce a potentially more focused image in the direction parallel to the slit, from what I know about how diffraction.

Though also interestingly, I decided to read some about slit pupils in animals, and apparently one of their advantages is that they enable multi-focal optics to compensate for the chromatic abberation issues that come with the shallow depth of field of large pupils for low light vision

And honestly in that light the both very large and slit-shaped pupils of yinglets make a lot of sense. Their sleep pattern will lead to a lot of activity at night and in twilight, and I could easily imagine especially lesser yinglets being active mostly during twilight to avoid daytime predators. Plus, the nights on that world are probably substantially brighter than those on Earth thanks to that huge nebula taking up a good chunk of the night sky.

slit pupils are not small enough to produce diffraction grating style effects. narrow pupil, better resolution; wider pupil, less resolution. if the pupil isn't round, but instead a long oval, it's going to have better resolution for the axis perpendicular to the long axis. that's just physics, really

also yes, they're ambush predators whose closest relatives are low to the ground, at about half their height or less (the lesser yinglet, which we only ever see in an early field guide). their slit pupils make the most sense in that light, though they also don't hurt their vision that much in full light, and they look cool tbh

edit to add: the big advantage slit pupils have is depth cuing from the way the image blurs ahead of and behind the focal point. it becomes very apparent when one's fully in focus, which is part of how cats do a "TARGET ACQUIRED" especially in low light
