If the blind woman will ask you what is the color of blue how can you describe the color of blue ?

If she has been blind since birth, then I don't think there is anything you can equate a colour to, my suggestion would be to describe it as a feeling, "blue" is how you feel on a cold day!

if she born blind i don't think she would understand the description so it's better to explain by feelings (blue is like: when u feel so hot & drink a cold water)

 

I would tell her to feel calmness of mind.The feeling when nothing has moved her.

The closest color to clear, it usually appears in places that are supposed to be transparent, like the sea and the sky. It is the color of depth

it's sky color .!

Think of the cold stinging sensation of ice... a brief breeze during summer that you wish it could have gone the whole day... the feeling that engulfs you when you are sad... the crack of lightning during a storm... remember, blue also represents sadness...

i would descibe by giving her a glass of water which is cold and feel that chill and let her feel the sun on her face which exactly feels the color of blue...
