• Notable artists and designers have discussed how limitations in color vision can inspire creativity in using shapes and textures.

History

• Early studies on color blindness and achromatopsia date back to the 19th century when scientists were first exploring human vision.
• In the 1920s, the term was gaining traction as more was understood about the human eye and its functions.

Psychology

• Many individuals with achromatopsia report relying more on shapes and brightness for recognition, highlighting how the brain adapts to loss.
• Studies suggest that those affected often develop enhanced abilities in contrast recognition, compensating for their lack of color perception.
