I use red as well, but that represents pure evil (eg the demonic "corporeals"). I hashed this out with Gemini a few hours ago:
Once Connor's been stabbed by a supposedly demonic dagger, his eyes begin to turn increasingly intense shades of yellow, accompanied by ever-increasing burning pain in his irises, bleeding from his eyes, and he's incrementally losing his sight. That'll require changes to the prologue, but it's a more complete consequence of him trying to use his powers for good: the poison surges back, resulting in the aforementioned consequences. It isn't until he "loses" his battle against the poison that his eyes go red, his sight is restored, the burning and bleeding cease, but he is now lost to evil.
The other alternative I'm considering is to use black as the color of evil. It's less derivative. So, when a corporeal attacks, its eyeballs would go completely black. In Connor's case, his attempts to use his powers for good still nets a glowing blue color for the irises. In extreme cases, like when he fights the locusts, the glowing blue extends to the entire eyeball.
Once he's done using his powers, the poison's effects surge back, enlarging his pupils, and causing the other effects noted above. As the poison gains more and more control over him, his pupils will continue to enlarge, pushing the irises back until the entire whites of his eyes are black too, like the corporeals. Anatomically possible? Of course not, but I had Gemini do a few images of a young adult male with black irises vs black eyeballs. The later was definitely more scary looking.
Funny thing, though. Gemini choked as I got too specific with the details because it was bumping into its safety rules that disallow it from creating anything potentially offensive (eg scary depictions of teenagers). That led me into a lengthy discussion about the stupidity of its current rules. It admitted for example that it could not even produce a picture of a kid with severe acne for a medical paper or news article, although I don't know if the same applies to a chat session that didn't include my earlier requests to create hideous corporeals vs an angelic-looking teenager with black eyeballs. ![]()
i actually got the idea from my cat. When he gets the zoomies, he typically spends a lot of time running around in my basement, where I don't normally have lights on. When he gets back upstairs, he looks downright demonic because his black pupils have grown so big in the dark.
I'll have to include an acknowledgment to Gandalf the Beige for the inspiration.
