The âHuman White Balanceâ in the Brain. Human visual perception does not work like a technical measuring instrument that projects signals from the eyes on some kind of âmonitorâ in the brain. The pictures we perceive are created in the brain and after the brain has compared the signals from the eyes with known patterns and colors.
There are two types of perception; the way you see yourself and your world and the way others see you and their world. The only perception you have control over is your own. It is just not possible to control the perception of others. For example, consider the temperature of a room. You perceive a room as being comfortable while someone else thinks itâs too cold.
