According to Andrew Lotery, professor of ophthalmology at the University of Southampton School of Medicine, UK, the difference in people's color perception may be due to lighting conditions, photo viewing equipment, even age and gender. of viewers.

Lotery explains each person has a different set of genes, creating a sense of color in red, green, and blue. Because these genes are located on the X chromosome, women tend to develop more variants. As a result, they can feel more vivid, more sensitive to special colors.

Lotery also emphasized that some people have superior blue-sensing genes, so they can see that the color is clearer or fainter.

In addition, as people age, people's color perception changes. The irises gradually become yellow due to aging and sensitivity to blue. This affects the perception of color intensity and explains why older people may often see things that are green and black rather than yellow and white.
