A nice question. To the best of our measurements, the cones are not monochromatic in their response. This is they actually respond to a broad region of colours, and some of this response may even overlap with an adjacent colour cone. This is nicely shown in the article on Cone cells in wikipedia.
You have about 4.5 million cone cells and 90 million rod cells in each eye.
Your eyes are actually an extension of brain, and it is in the brain that the discrimination between all the colours and shades is made.

How can you explain the fact that we see a great range of colors even though only three cone tpyes exist?
This is because multiple cones may be activated at the same time allowing us to see many colors. The three cones may not always be activated to capacity, and the blending of the activations allows us to see variations of color, just as you could mix different amounts of paint colors (red green and blue) to create many colors.
