What color are orcas' eyes?
In short, mostly brown. In long, it's a bit complicated as Killer whales (and for that matter, all cetaceans) have multi coloured eyes! Unlike us humans, who have a singular coloured iris and a white sclera, cetacean eyes come in more flavours. Their iris is circled by a pale ring of varying colour, and the surrounding sclera is more often than not coloured too, sometimes even bi-colored. I have actually been working on a cetacean eye-colour-chart thing so I have some neat illustrations ready.
Here you can see the components that make up a cetacean's eye. It should be noted though that when relaxed, the eyelids cover much of it, leaving almost only the iris visible. As an example: a Harbour porpoise (Phocoena phocoena). On the left a clear view of the eye in its totality; on the right as visible in life.
Onto the whale in question. All cetaceans have beautiful brown irises: in many it is an unbelievably rich reddish hue when sunlight hits it directly. In shadow or underwater it looks more subdued though. Then comes the pale ring which in Killer whales is quite variable: in some animals it is very pale, almost white, while others have beautiful bright blue rings. The sclera appears two-toned in blackfish as far as I've seen. Killer whales have a rather modest dark brown area of sclera around the iris-pale-ring-combo, with the surrounding "base" sclera reddish pink. For comparison, False killer whales (Pseudorca crassidens) have a bit more substantive dark brown sclera area, with the surrounding sclera a striking bright red.
I hope this answers your question! This makes me want to finish this chart haha so maybe that'll come soon-ish in its totality.
