Blindman See.

We all know that Apples are RED and the skies are BLUE .But have you ever wondered how red or blue would actually look or even means to a blind dude ? I mean in the 1st place how do u even start to describe red or any colour to a person who has never seen colour in their whole entire life ! How does it feels and how does the world looks like through a blindman eyes ? How is our world through their perspective ? Just think bout it, maybe the apple or the skies that they know of is very much different than the real thing..maybe the apple they know is more "blue-ish" rather than red ? hmm..Interesting aint it .
