how would you describe the color red to a person?

I don't know really, the only thought which came in my mind was that I would tell the blind person to "look" up straight in the sun, I usually get red sparkles in my eyes after getting sun dazzled. Maybe the blind person would see the same red sparkles. But how would he/she know that's the red? I have no idea.

In addition to the touch method of describing, I think I would also try to describe it through emotions. I would tell the person to recall feelings of extreme anger and/or passion and that would be red.

I think I'll connote it with FIRE... Red is somehow a fiery color, it is use to described hot surfaces and stuffs. I think connoting it with FIRE is the best way to describe it in a blind person.

I would tell them that it looks like fire feels. That's the best I could come up with.

Helen Keller, who was blind and deaf, learned about colors when her teacher related them to touch. She had Helen touch something hot and signed the word "red" against her palm, then she had her touch something cold and signed "blue" against her palm.

I would ask him to describe a feeling related to love or danger and tell him that it would be something like that.

I've come across this question before, but after years of thinking about it, I think I would say that it would be useless to describe colors to anyone who can't see them. They just wouldn't be able to relate. I know that's not what you or anyone else who asks this question is looking for in an answer, but that's how I realistically see it. A blind person who has never seen colors would have no use for them as they would be meaningless. The only thing they might need is some help with color-coordinating their clothes so that they don't look strange to sighted people.
