I wouldn’t say albino Kuros are impossible juuuuuuuust yet, they only seem so for now. The scale color is akin to magic/darkness purposes, but a Kuros with albinism could still have symptoms of it. Such as sight issues, loss of pigment in feathers/fur/hair, changing the protection the scales can provide (making them susceptible to sunburn, granted the sun doesn’t shine much on Kurosia anyway, so it wouldn’t hurt them that bad. Just makes it difficult if they do have to fly in sunlight), etc.
I think, if anything, an albino hybrid Kuros could happen and they didn’t have much darkness within them to darken their scales. But a pure Kuros, not just yet i’m afraid.
