What is the colour of the wind?

There was a blind man in one of the villages in Kwazulu-Natal, this man was very clever and he wanted to prove and try everything, he wanted to live life as a person who is not blind. He used to ask lots and lots of questions and he was very good in doing the research of anything he wanted to know, he loved the nature. He knew that the sky is blue, water is colourless, he knew that he cannot touch the sky physically because he was told that sky is far away, he could touch water, he could feel the wind and the other that he heard two of his friends talking to one another …look at you the wind really changed you, just go and take a shower you will be back to normal… the blind man asked what is the colour of  the wind…
