How do Humans Perceive Color?

In this video, we discuss how humans perceive color. We learn about different, competing theories of color vision and we experience a few demonstrations (e.g., afterimages) that illustrate the strengths and weaknesses of these theories.
Light: A form of electromagnetic energy that has a wavelength, which determines its color.
Trichromatic Theory: A theory of how we perceive color which suggests that our color vision is based on three primary colors-red, green, and blue-since we have three different kinds of cones that are each maximally sensitive to the different wavelengths associated with these colors.
Monochromats: People with a specific form of color blindness in which they only have 1 out of the 3 different types of cones, resulting in total color blindness (monochromacy affects 1 in 30,000 people).
Dichromats: People with a specific form of color blindness in which they only have 2 out of the 3 different types of cones, resulting in partial color blindness (e.g., red-green color blindness).
Opponent Process Theory: Another theory of color vision which suggests that we perceive colors in terms of three pairs of opposing colors: red vs. green, blue vs. yellow, and black vs. white; afterimages always appear in opposing colors, providing evidence for this theory.

7:14 I didn't see a red, blue and white American flag. I saw a white and kinda black flag. Only after u said it's white and red, I began to see it a lil bit. 😭😭😭 Is my vision wrong? 😫 8:02 OK this works.. 😖👌

It definitely looks like we perceive 4 pure colors (plus white) and the ratios between. The one limitation of using after images to show it is that some cones burn out quicker than others. This means you may still have one cone type activated in both scenarios, resulting in a skewed experience.

According to opponent process theory how do we see pink or any other colour not mentioned in the theory ?
