Colour - Gender Differences

Do men and women have the same colour vision?

We know that there are many differences between the sexes - both physiological and psychological. Could it extend to colour vision?

Approx 2-3% of the world's women have additional visual equipment (a fourth core in the eye) that gives a significant increase in colour differentiation - similar to the super-vision in birds.

A recent study revealed that women have a better ability to discriminate colours in the red-orange spectrum. Researchers found that the gene that allows people to see the colour red comes in an unusually high number of variations. This may explain why women see crimson, vermillion & tomato, but it is still just red to a male.

Radeloff's gender-based study in 1990 found that women preferred lighter, soft pastel colours and men prefer brighter, cool colours.
