One thing that struck me strangest was seeing a picture gallery of Rh(D) negative individuals years ago and noticing an unusually high frequency of hazel eyes.
Or was that what I really saw?
According to Vision Boutique:
What Are Their Differences? In short, the difference between hazel eyes and those with central heterochromia lies in how the melanin is dispersed. Hazel eyes can appear to be two different colors, but they blend together at some point, where central heterochromia has two very distinct rings of color within the iris.
