Does everyone see the same color?

The short answer is: we don't really know.

Colors do not "exist" so we cannot say who sees colors the right way. Colors are brain responses which are created when light hits our eyes.

What can be said is that, at the basic level, most of the time we probably all experience the same color sensation when viewing the same object under the same lighting conditions. This basic assumption allows us to communicate easily about the colors we see. However, there can be some differences in color experience and perception among individuals due to factors such as different photoreceptor responses in the eyes, variations in the neural processing of color information in the brain, individual experiences and memory associations with colors, and even cultural factors that can influence how we categorize and label colors.

Some color vision deficiencies, such as colorblindness, can result in differences in color perception, where certain colors may appear different or confused. Additionally, some individuals may experience atypical or unusual color perception due to neurological conditions or certain medications.
