Talking of pigments...

Everyone here is aware that we can't *really* see the whole visible
light spectrum, right, that we can't tell the differences between some
colours and combinations of others?

For instance, if we see pure yellow light, it stimulates red and green
receptors in equal measure in our retinas, just like a mix of red and
green light would do. And in both cases, we presumably experience the
qualia for yellow.

Why? Why don't we experience red and green qualia at the same time,
when we see a mix of red and green?
