Document Summary
How do the colour-blind perceive the world differently from the rest: unique case study -- involves a woman who was colour blind in only one eye, with her other eye being of normal colour vision. She was shown wavelengths of light between 400nm and 700nm to her colour-blind eye and asked to match the colour that she perceived to a range of colours that she looked at with her normal eye. For the colour-blind eye, all wavelengths between 500nm and 700nm appeared to be the same shade of yellow (or roughly 570nm in her normal eye) When her colour-blind eye was presented with wavelengths between 400nm and 500nm, her normal eye perceived them as the same bluish colour of around 470nm. So this woman was red-green colour-blind in one eye and only able to see blues, yellow, and shades of grey. In conclusion, red-green colour blindness limits the shades of colours perceivable.
