How do you explain the color blue to a blind man?  

I hear also this question on job interview in a call center. If you are a blind man then if you feel sad, unhappy, glum, doleful that was blue. If you are feeling blue(sad) all you have to do is look at your feelings.lol. happy Mylotting!!!

i will tell him that blue is cold, but not snow and ice. blue is calm, but also waves like the sea. blue is lonely, but twinkles like stars that u can feel its bright.

~ Hi! The answer, at least for me is very simple. You can't explain a blind person the blue color, because he has no idea for the world and for the colors, so we can not explain to such person how the blue color looks like! ~

Seeing the light reflected off of something that can be far away determines color. Light is made up of every kind of color, including blue. When all colors of the light are absorbed into the object accept blue, the light you see is blue. Things that are blue include the ocean, the sky, ice, and blueberries. So when someone see's blue, it reminds them of those things. If you feel something wet, or cold, and it tastes like blueberries, then you are sensing all the forms of blue. Can you see it now?

Well its a fact that a blind person will never know what blue is cos everyones blue is different. Some may say its a colour or sadness but its also a colour of coolness. You know what. The best answer is to say its a colour which you will one day see when science or God heals your eyes.

I would explain blue by letting him touch ice. Then red by letting him touch something hot. That way, the blind man can associate it to something he can sense.
