I do think that diet and general health can influence your eye color, but not to where it's going to actually change the color. I would say their eyes appear different colors because lighting is just different throughout the year.

I don't really think people's eyes change colors with the seasons.

Nobody really has a fixed eye color (really nothing has a "fixed" color). But if I have true blue eyes and wear a green sweater, my eyes will not appear green at all because there is no green in my eyes to be "brought out"-so instead my eyes will clash with the sweater.Įverybody's eyes will appear different colors depending on the lighting as well as the environment. If I wear a blue sweater, they will appear blue, because your eyes will pick out the colors that match. If I am wearing a green sweater, it will bring out the green elements of my eyes, making them appear green even though they are normally closer to blue-green. When your eyes look at something and see a certain color, they automatically and subconsciously look around the rest of the scene for other things of that same color. And natural light does change in temperature throughout the seasons, so everything looks different colors depending on both the season as well as the time of day.Ĭlothing also has an impact. So not just eyes, but all things appear different colors based on what kind of light they are reflecting. Indoor, artificial lighting seems warmer and more red. Light also has different "temperatures," which makes things appear different colors, including eyes. (I believe green eyes are basically somewhere in between blue and brown, meaning they have some pigment in front of their irises, where true blue eyes have none, and brown or black eyes obviously have the most.) In the dark, they no longer have blue eyes (whereas people with brown eyes will always have the pigment that makes their eyes appear brown.) It is because people with blue eyes lack a certain pigment in front of their irises that the light bounces around differently creating the appearance of blue or green eyes. (All irises are actually the same color-dark grey-it is the pigment in front of the iris or lack thereof that creates the appearance of different eye colors.) So a person with blue eyes does not really have blue eyes-they have eyes that appear blue in certain light. If you dissected a blue-eyed person's eye, you would not find a blue iris the way you would think.

For eye colors other than brown, the color is not caused by an actual pigment in the eye.
