Quick Summary

Deuteranopia, also known as green blindness, is a form of color blindness where an individual has a reduced ability to distinguish between colors. People with deuteranopia are considered dichromats, meaning they can perceive the spectrum using only two primary colors instead of the typical three.12

Specifically, individuals with deuteranopia match all colors using a combination of red and blue. This means they cannot differentiate between reds, oranges, yellows, and many greens. Their perception of white is a mix of red and blue, which appears purple to someone with normal color vision. Deuteranopia is a type of red-green color blindness.2
