Regarding ayleid specifically, their skin is darker than that of altmers and their eyes are more consistently lighter, almost always with blue tint. Yeah, they still look like a generic elf, but their appearance is clearly separated from that of altmers
(slapping the other ask on this one since they're related)
Yeah I like that there's something visually different about the Ayleid's from the Altmer/Aldmer (and by eso design standards, skin tone is about as far as they can significantly go). It's mostly based on how Dynar looks, but I also like to imagine they are more square and boxy-er looking than the Aldmer/Altmer (less like your stereotypically tall and graceful fantasy elves) to set them apart.
And I agree I like the yellow Dunmer lol. I mentioned it briefly when I did the ear headcanon thing, but I pretty much picture Chimer as a mix of Dunmer and Altmer characteristics, so it works for me!
Speaking of, when I did the ear headcanon thing I also did this skin tone thing for my own reference as a sort of mapping of general trends. Might as well post them while we're here
these tags are everything to me. THANK YOU. i thought i was alone!
