• Question: How do we know that the colours we see are the same as everyone else? I know the wavelengths are the same but you can't describe the actual colour that you see...

      I’ve often had that discussion with my wife 😉
      You’re correct, we cannot say for sure that the colour you see is the same as what someone else sees. It’s down to how your eyes work and how your brain processes the information.
