I just met a person, a young woman, who actually had blue-green eyes. The eyes were mostly blue with a bit of green in the center. What a great color! I think this may have been the first person I have ever met who had blue-green eyes. I would think that blue-green eyes would be nearly the ultimate in Whiteness. Those two eye colors are generally found exclusively in Whites. The combination of two exclusively White traits is quite a sight to see. Many of the most beautiful women around are said to have blue-green eyes.
Some variations on blue-green are aquamarine, teal, turquoise (my favorite), and cerulean.
Is this combination common?
My own eyes are mostly green (an exclusively White color) with a bit of brown in the center, so they end up being called hazel, but they are mostly just green. I used to wear green contact lenses and that made them even greener.
There is typically a contest between blue and green eyes regarding which are more beautiful. It is often resolved in favor of green, which are considered the most beautiful because they are the rarest.
