Question: is it possible that we could all be seeing different colours, so the colour I think is red, someone else thinks is blue, because we have all grown up being taught that the sky is blue, etc.

  Hi @fatlouietwin and @nhanlon12
  
  I am FASCINATED by this question. It’s more philosophy than science. I think it’s probably quite likely that we all see things a bit differently, because of the way our eyes are made up, for example. However, I can’t see how you’ll ever be able to answer this question, because you can never see something through someone else’s eyes and mind, and even if you could you’d have to look at that with YOUR eyes and mind anyway…
  
  Ooh, I’ve confused myself now 🙂
