HELP i just realized something while thinking about orcs. animals often have the color of their surroundings to camouflage themselves better. for example, wise polar bears, blue whales, green parrots and so on.
plants and nature are predominantly green. but are there also green mammals?

@Mabelz Algae grows on sloths, so they’re often called green, but I am not sure if that counts

that said some animals make themself green. for example the sloth shown here has algea in their fur.
btw most carnivours has shitty color vision. so camouflaging by color is useless. the shape and texture is far more important. hunters more often try to camouflage by color since herbivours have usually better color vision. especially if they need to detect tasty food.
btw polar bears are black to increase their body heat. their fur is colorless but hollow. the light gets reflected so many times they "appear" white. if u take a single hair there is no white pigment

apophis@akko.disqordia.spacei wonder if it would be possible for mammal hair to develop iridescence but from what i know about how mammal hair follicles work that's probably out of the question as well (barring many millions of years of basically evolving into feathers)

apophis@akko.disqordia.space> shitty color vision
also of note: tigers are fully camouflaged against their normal, non-human prey https://old.reddit.com/r/Damnthatsinteresting/comments/snqs81/tigers_generally_appear_orange_to_humans_because/

@Mabelz I actually looked into this a few years ago. The reason has to do with melanin and it's quantum properties. There is melanin in your irises, but it's actually the microstructures of melanin interacting with light that gives color, which is how you can have eye color change from hour to hour.
Skin is too large scale for those to happen, so you get pink-beige-red-brown-black spectrum. There are two melanin types, a red-skewing one and a black-skewing one.
Fur is also too large scale for microstructures. Feathers, absolutely; most colors you see there are due to microstructures not pigment.
