– What happens when an artist mixes paint for a painting? Are the pigments actually changing physically/chemically? What is actually happening to make the paints change color?

I’m very surprised not to find rods and cones in the answers.
Our eyes contain what are called rods and cones. Rods are for night vision and cannot detect colors, so I won’t go into detail other than to say they represent 95% of the detectors in your eye and primarily fill the remainder of your eyes.
Cones are what detect color and are primarily used for day (bright) vision. There are three types of cones that each detect either red, green or blue (RGB). This is why monitors and televisions have clusters of “pixels” that target one of these cones in your eye.
Any other color you “see” is actually an interpretation your brain makes of the relative percentage of the amount of red, green and blue in what you are looking at. “White” is seen (interpreted) when there are roughly equal amounts of RGB, except when there is no red, green or blue, which is interpreted as “Black.”
