Geen is also a combination of at least two different colors. It is NOT it's own color.

What about ORANGE? That is a secondary color.

Hey...what about browns and greys? They aren't one the spectrum either, but we see those colors and they are a mixture of two or many more colors.

So HOW do we see as many different colors that we DO see? There's nothing in the article about that.

We see different colors due to combinations of light frequencies,

Any pigments does not produce a single frequency. It emits a combination of frequencies.
