Day 8. Curious case of colour blindness


I was involved in a curious discussion about colour blindness with my flatmate a few days ago. He passed on to me the thought which had kept him puzzled for a very long time. And now I am really struggling to shake this thought off my brain.

It was a long discussion in which We were discussing if a person is colour blind and he is seeing the colour red as green then how would he know what colour red would look like ? For him the red colour would always have been Green. It can be answered if someone tells him that he is telling two colours Red and Green as one. It was easy.

Then my friend proposed a point “What if it is possible that the colour Red that we are seeing as Red is seen by another person as Green and for that person that Green colour is Red. And the another person has been calling the Green colour the Red all the time because he is seeing the Red colour as Green always. And it is the same with every colour for him. What if he is seeing Yellow as blue, black as white, orange as purple. And calling what he is seeing what they have been taught.

What if all of us see an apple with different colours and call it red because we have been taught that the apple is red. This way no one would ever known if they are colour blind and seeing an apple as red , green or blue but each of them calling it red. In this case for first person the red is red , the second person know green as red and the third person call blue as red.

He simply added what if every eye on this planet is watching all colours differently and calling it what they have been told in their life. But no one questioning or doubting the skills of identifying a colour because for everyone apple is red, even if they see it in a different colour.

Confused Right ?

I am never satisfied with what I have, and never Doubt on what I can conquer. I do not just look only in straight direction, because the world of wisdom is walking beside me and I also discover the sully soul on my other side, I am a camouflage of both. I turn around and try to walk backward to see what I keep within, deep, behind my back and accept the strokes wind puts on my face and make myself ready to get shocked any moment in life, because Things will change their shape and dimension in coming years, Good will become bad and bad will become the best. because it is what I have seen yet. Even me will not remain me, but my instinct will never change neither my love for certain things. So I surge up into the territory of stars, out of this world and try to find who I am today ?

  • Interesting thoughts! So much of our perception is conditioned by society and culture – it is learned not intrinsic. So you can see how our view of beauty, color combinations that work, even food that is tasty change with time…..Thank you for sharing this. πŸ™‚

  • Green is Green and Red is Red is when we go into the traffic lights… Now, for world it is known that when it’s Green, we move and when the color is Red, we stop. If a person moves when the signal is Red, he knows that something is wrong and seeks professional help.. .. Now, that is where the test for color blindness, (the picture shown above) is useful and ‘the’ person is differentiated from others… Hence, it is mandatory for every driver to pass the test before being granted the license to drive…
