Fun random ! - are hazel eyes purely and truly just one i don't think ! all my stuff below kinda proves they aren' pls read, i know it's long but it's ! if you don't think i'm right, then pelase back yourself up with some sort of information to prove yourself wrong. easy scientifically: hazel eyes are due to a combination of rayleigh scattering and a moderate amount of melanin in the iris' anterior border layer. hazel eyes often appear to shift in color from a brown to a green. although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green. another scientific statement: no two pair of hazel eyes is exactly the same. some people have lighter features of green while others have darker features of brown. ocular scientists think hazel eye color is a combination of greens, browns and blues but if truth be told, they aren't exactly sure. we do know however, that hazel is considered rare. in my own personal life and opinion: i have hazel eyes. sometimes mine appear orange, other times brown and at some points, almost like a bunch of colors mixed together like a poop-ish, type of color. one of my relatives has hazel eyes too and she calls them "mood eyes" i can't contradict her either because sometimes, depending on my mood, my eyes change color, lol. to sum it all up: i do though, consider hazel eyes as a rare kind of eye because there is no specific color.
