Yasser is colorblind and is unable to see colors the same way as his wife. Describe which theory of color vision best explains this deficiency and explain which theory of color vision best explains why he might see an afterimage.

The theory of color vision which best explains this deficiency explained above is:

According to the given question, we can see that we need to explain why Yasser who is colorblind is unable to see colors the same way as his wife and why he might see it as an afterimage.

As a result of this, we can see that the trichromatic color theory has to do with the eyes seeing red and green cones and is usually noticed in men and it explains why Yasser would look at a red image for some seconds and when he looks at a blank image, the imprint he would see would be green in color.

The answer is below

Explanation:

The theory of color vision best that best explains this deficiency is called TRICHROMATIC COLOR THEORY. It was originally proposed by Thomas Young and later refined by Hermann von Helmholtz.

Here, Yasser’s color-blindness is associated with deficiencies in various cones. The most probable are red and green cones because of their high chance in men than women.

The theory of color vision best explains why he might see an afterimage is known as OPPONENT - PROCESS THEORY. It was originally proposed by Ewald Hering.

This is based on the principle that supposing Yasser, stared at a red image for a while and then stared at a blank white page, he would likely see an imprint of the image, but in green.
