The Purkinje effect, also known as the Purkinje shift, refers to a phenomenon in human vision where the perceived brightness of colors shifts under varying light conditions, particularly in dim or low-light environments. Under bright light conditions (photopic vision), our eyes are more sensitive to longer wavelengths of light, such as yellow and red.
