Testing your colour vision
Do you think that you have excellent colour vision?
Colour blindness, also called colour vision deficiency, results in difficulty distinguishing between colours. Colour blindness is most often found in males. The ‘x’ chromosome carries the most common genes related to this condition and females, who each have 2 ‘x’ chromosomes, have a second chance to develop a fully functioning set of cones.

Globally, colour blindness affects 1 in 12 men and 1 in 200 women. In the UK approximately 4.5% of the population is colour blind - the majority being male.
This article describes how graphics and maps can be presented more clearly to include those with colour vision deficiency.
