Purple

"And then Jenny said the eyes were like, this weird purple color? But Stacy swears they were more blue. Usually, glowing is yellow or green, right?"

"Purple? Is that the only reason it's weird? My cousin saw red ones last summer."

"Blue eyes glow red in light! That's probably why. Purple seems weird, though. I don't think purple eyes is normal. That's creepy. Were they staring into her room or something?"

"It probably wasn't even eyes, then. Maybe someone was practicing light orbs."

The gaggle of students devolves into a debate about supernatural eye colors that would put a Pinterest board to shame. Not a single useful detail emerges from their chatter.

Penelope extricates herself with practiced grace. "Well ladies, this has been absolutely fascinating, but we should get going."
