Thanks Nina @ninahaskin. It would be interesting to know how people with heterochromia describe the eye color on the driver’s license. Maybe it doesn’t matter, they just pick one color or the other.
I wasn’t in the same classroom as the girl with the eye heterochromia but knew her younger sister.
Next time I'm at the Department of Revenue I'll ask one of the friendly employees there how they handle listing eye color of those with heterochromia on driver's licenses!😀
