Question

What color is the sky to a color blind person?

Answer 1

Colour blindness: It is defined as the inability to see or identify colours such as blue, green, or red.

1. When a person has red-green color blindness, blue appears normal.
2. But, when a person has blue-yellow color blindness, it is difficult to tell the difference between blue and green.
3. There is no color seen with total color blindness, often known as monochromacy.

Thus, a color-blind person sees the sky as blue however, confuses between objects that are red or green.
