The best thing about being colourblind is that rubix cubes are a LOT easier. But what is not easy is being a chameleon. Above is the just 3 examples of the Ishihara test to determine whether you are in the 1 in 12 men or 1 in 200 women who are colour blind. On the plus side, I discovered today in my ‘colour: art and science’ lecture that 20% of women have a 4th cone in the eye instead of just the RGB 3. This means, yes, WOMEN ARE SUPERHEROES.
