> As a side note, I do wonder how differently a child would perceive color if they were taught more than 7 colors in preschool.

Just as all other modern schooling, the teaching of colors is done deliberately order to dumb down children and starve them from their natural ability to learn.

A child will learn at least dozens, if not hundreds of colors, if they are allowed to and taught. This has a real impact, because unless you learn this, it can be very difficult as an adult to be able to actually see the difference between colors.

But instead idiots make toys with only simple prime colors, and even playgrounds. Even though children themselves prefer more diverse and interesting color schemes.

Although after a few dozen color names, I think children are more benefitted by learning more about color theory such as physical paint mixing, digital mixing like RGB and HSL, and physical light effects on colours.
