So fun fact: I decided to update my blorbo Night-nymphs as a species aaand: Eclipse and Moirai have blue blood now! Like that type if crab I forgot the name of! And! This, is why both Eclipse & Moirai nymphs have blue skin! :) Pirin has albinism, so he's paler n got poor eyesight a bit so.. when it's too bright he kinda struggles; things look like bit blurry shapes of color to him.
And his pupils, eyes and sclera turn blue due to stress and capillaries popping like that one lizard type. So the more stressed he is, the bluer and darker his eyes get 'til becoming this deep, near-black blue. Kinda like abyssal depths. ...Big contrast to how bright & clear grey his eyes are when cheery. Normal color is, pearlescent - or just light grey that can be described like that.
