Rainbows and Colour Blind People

How Do Colorblind People See The Rainbow?

Such people are known as being color blind and their state is the result of the inability of the eye to see and differentiate between different colors.

People who are completely color blind would see the rainbow in shades of gray – and perhaps they would see everything as either black, white, or a shade gray.
