When I was small, I knew that I had brown eyes. Certainly that's what was said in my family. My mother and I were left-handed and brown-eyed, my father and brother were right-handed and blue-eyed. That kind of symmetry appealed at the time. All the same, I assume I occasionally thought to carry out an empirical cross-check and look in the mirror, and nothing I saw there made me question the received opinion. I think it wasn't until I was at college that someone who had taken to staring into my eyes a lot happened to mention that they were actually hazel-green. Looking more closely, I saw that they were indeed - although there was also some dark brown there still, and even a fleck or two of blue, and yellow, and slate-grey.
Ever since then, I've not known what colour my eyes are. If I had to fill in a tick-box form describing them, I simply would not know what to say.
As an experiment, I just took three pictures of my left eye, about a minute apart: under artificial light, in bright sunlight, and indoors in natural light.
How would you describe this eye, in terms of colour? (Its fellow is similar.) I thought of doing this as a poll, but I don't want to make this into a leading question.
