Ok, you have a point, I could have mentioned all other possible gray tones. But that is why I posted the chart, which is based on the Martin–Schultz scale, so you all could see all possible shades for eye color. I used brown eye as an example; 1st because for me, as someone with amber eyers, this is somewhat personal; 2nd because brown eyes have a way broader spectrum than grey and other colors, and yet, people tend to group it as just one thing. Hazel and green eyes have no other scale under the chart/martin-schultz. My point was exactly that, people seem to have no clue whatsoever when defining their own eye color and, for that reason, tend to overcomplicate (or oversimplify) things way too much.
