There are infinite colors.. Duh...

Ofcourse it's been many many years since I had that art class in elementary school.

It's cyan, magenta, and yellow. That's not true anyway. And it's not true that light is only red, green, and blue. It's just that we percieve combinations of the primary colors of light as in between colors.

RYB refers to the additive pigmented color system.

Ideally, when looking at the "possible" colors, we should be looking at how those colors enter our eyes - IE, light.

Light is composed of 3 different colors, red, green, and blue.

There exists an infinite number of combinations of those three colors.

Regardless, humans cannot see them all.

CMY refers to the reflective subtractive color scheme.

Technically, RGB, CMY, and RBY are all correct colors schemes, but they differ in what composes them.

What you perceive of as color is visible light, between 300nm and 700nm in wavelength. In that range, there are an infinite number of colors.

EDIT: Actually, what you percieve of as visible light is not just e-m radiation between 300nm and 700nm in wavelength, but also various combinations of those wavelengths. I just realized that after remembering chemistry and physics lab spectroscopy tests. The resulting conclusion, that there are an infinite number of colors, does not change.
