"It's red! Pure red!" "No, it's orange red!" "What are you talking about? It's pinkish red!" "Not a chance! it's dark red!"


How many times have you heard this in your everyday life? Quite a few, I'm sure. I bet you've said any of these yourself pretty often!



So, why does this happen? 

Why do colours look so different to people?

The reason is "COLOUR VISION".


What, exactly is "Colour Vision" and how does it work? What is "Colour" in the first place?




"the appearance that things have that results from the way in which they reflect light."






"perception of and ability to distinguish colours".




It is very simple.



The human eye receives light and it converts it into an electric current, which is transmitted to the brain, as a nerve impulse, along the optic nerve.

Your brain receives the impulse, checks it & analyzes it.



Up to here, it's all anatomy.

After that, comes psychology.

After receiving, checking & analyzing, the brain interprets, evaluates and finally decides whether to accept the impulse-stimulus as positive or reject it as negative.

Want proof?


  • Have you ever disliked a painting although you liked its subject, without being able to explain why?
  • Why do you find certain colours in painting particularly pleasant & not others?
  • Why do you like different colours than the ones other people may like?

In other words, Colour Vision is a twofold process: 



Both feelings & ideas.

Both perception & ability.




What's the answer?


People see colours differently, because they filter them through their own imagination & psychological world, which are unique in every person. Therefore, their perception of colours and consequently of art, is a result not only of what they see in a painting, but, mainly, of how they interpret what they see in a painting.
