Do blind people have ideas of color?
Though blind people lack the sensory experience of colour, they can nonetheless – thanks to language – form rich and accurate colour concepts, Caramazza notes. Earlier work has shown, for example, that they know that orange is more similar to yellow and red than to green or blue, Caramazza says.
Can a born blind person imagine colors?
Public Domain Image, source: NSF. Yes, blind people do indeed dream in visual images. For people who were born with eyesight and then later went blind, it is not surprising that they experience visual sensations while dreaming.
How does a blind person see color?
Instead of seeing green and red as distinct colors, the person sees them as being very similar, thus the resulting color confusion and other frustrations. Color blindness is caused by a change or reduction of sensitivity of one or more of the light-sensitive cone cells in the eye.
What is a congenitally blind person?
At the same time, I adopt the term “congenitally blind” to refer to people who are unable to see since birth or lost this ability in the first two years of life, and therefore have no visual memory and imagination, which in this context clearly distinguishes their expe- riences from the perspective of those blind …
What is white if not a color?

Can a sighted person see the same color as a blind person?
What is remarkable, Caramazza said, is that despite those differences in how the blind experience colors and how they are represented differently in their brain, the blind and the sighted are able to understand color in similar ways.
Can a blind person describe a physical object?
And the same, he said, is true for blind people seeking to understand color. “You can use language to describe things that are physical,” he explained. “If you were blind and I wanted to describe a cup to you, I could say it’s a hard object that’s concave and it’s nonporous, so you can put liquids in it.
How does a blind person learn about Red?
“The way [a blind person] learn [s] about red is the way you and I learn about quarks, or about concepts like justice or virtue — through a verbal description or use in verbal contexts.”
What do blind people use to describe quarks?
With no way to directly experience what something like quarks actually are, Caramazza said, people lean heavily on language to understand or describe them — using words like “strange” and “charm” to describe quarks’ “flavors.” And the same, he said, is true for blind people seeking to understand color.
