Colour Blind Awareness Day

Colour Blind Awareness Day is a fantastic opportunity to celebrate and raise awareness of people with colour blindness. The date for Colour Blind Awareness Day was chosen because it’s the birthday of John Dalton.

John Dalton was a scientist who was born on 6th September 1766. He was the first person known to realise colour  blindness exists. As a scientist he became aware that neither he nor his brother saw colours the same way as everyone else. He thought this was because they had blue liquid in their eyes and Dalton left his eyes to science so that people could find out when he died. They didn’t! However, Dalton did understand that because both he and his brother were affected that their condition must be hereditary. Over 150 years later DNA proved he had inherited colour blindness. Colour blindness is also known as Daltonism in his memory.
