Aiyo, colour blind is your brain can't distinguish the correct color you saw.
You can call it evolved vision also.
Same for crabs or insects, their colour defination is different from ours.
Your genes have some changes therefore gives you monochrome sight.
It might be a confusion of colour also. A picture with too many colour your brain might not be able to filter and define them, therefore leaving them as the basic of all colour, black and white.
I don't know is this called phychology or what, but confirm something wrong with your eyes, brains for both lar. lol
