Origin of Chromium Oxide Green
The average number of colors that humans can distinguish is about one million. This situation varies depending on color blindness, or at the other end of the spectrum, depending on the "four color observer"; Rare individuals with genetic mutations can see up to 100 million colors. However, what humans have in common is their ability to recognize changes in green better than any other color. A short explanation for this commonality is the connection between human evolution and the past of our...
