Why are there more red than green, and more green than blue? I guess the biologic basis is not as over-simplified as simply the tuple (R, G, B). Is this a real image or is it computer generated? This is a pretty cool diagram, though. I wonder what the biological basis is for developing these three cones are, particularly.

Perhaps they arent distributed evenly and this is only a subset of cone cells?

If the colors of each cell corresponds to the type of light it detects, that would make sense since red stands out a lot to us, and having more cone cells that detect it would explain that. I can't tell if that's exactly what each dot represents though.

I am confused that it seems we have more red sensitive cone cells, but actually green light is the most sensitive color for human. Why?
I just learned the fact today that the distribution of these three types of cone cells is very different for each person. I think this greatly confirms the statement that colors are the result of human perception.
