Heh yeah, that's a cool recollection. I guess albinos may have them that way or pink-ish colored. Some hues of brown eye color can appear sort of gradually moving to reddish like in warm brown or chestnut brown eyes.

But that is precisely the point of TM's fixation with red eyes on divine characters, onis or characters with some kind of deep connection with the Earth/Gaia/otherworlds or underworlds. It's an unnatural eye color meant to express that they're sepparate from, or beyond normal mankind/humanity. It's stark reminder that you're dealing with a character from another realm, or with strong connections to it.
