Eye Color Changes: Myth or Real?
Do plural's eye colors change when they switch?
Note: this may be a mainly white body thing tied to lighter eye colors, especially hazel.
We believe so. When we were a kid we'd get all kinds of exclamations from folk about our eye color changing. They're between green, grey, a dark ring around the outer edge, more softened at times, and more definite lines radiating from the iris. But also eyes can reflect the colors you're wearing to some degree — so if various folk dress you in the morning, that could also affect how your eye color appears. When we wear green, our eyes seem more green than grey.
But yeah, I think there's some something about this.
And of course singular folk have their own "mood" explanations for this. See "may appear to 'change color'" on this page:
