It turns out there are other people in the world who appreciate black eyes. They have a Flickr group, which you can see here: http://www.flickr.com/groups/38534223@N00/.
As the English portion (it’s mostly Italian) of the site says:
This is the place where you can meet the most beautiful Black Pearls of Flickr . The black pearls are the dark and fascinating eyes of so many women and men, withdrawn by us impassioned photographers. Rare beauties as the black pearls
Some of those photos are of people with medium brown or even blue eyes. What gives?
