      The most common form of colourblindness is red/green colourblindness. This means that those people with it find it difficult to tell the difference between red and green and can easily confuse the two. This means that a lot of things appear as only blue or yellow.

      Apparently, it’s much more common for males to be colourblind than females – I’ve learnt something new today! 🙂

      One of the tests for colourblindness is to identify numbers in a sea of coloured dots – give it a go!
