Colour-blindness

I was talking to some children before half-term about colour-blindness. Here are some simple tests to see if you are like me. I am slightly red-green colour blind. This makes it difficult for me to tell the difference between some colours, like yellow and green on teletext.


If you are colourblind you should see the yellow circle. If you have normal colour vision you should see the yellow circle and a "faint" brown square. I can only see the yellow circle.

If you are colourblind you won't be able to see anything but dots. If you have normal colour vision you should see a boat. I can't see anything but dots.
