      There are lots of little light receptors in our eyes which send the message sabout what we are seeing to our brains. This reminds us of when we’ve seen colours before (for example, we see blue and think, ‘hey! the sky is blue! that is sky blue’). The surface of some objects reflect certain colours of white light, and they are what travel into our eyes. There are some differences we see in colours because of the way our eyes are made- we can see a bigger range of warm colours like reds or oranges. We can also be colour blind. This effects about eight % of men, and is due to a few error messages in their genes.
