When looking at a graph plotting "blue", "green" and "red" cones reponses to different wavelengths, you can see that any wavelength trigerring a response from green cones is also able to trigger a significant response from blue and red cones.
Excluding colorblindness, that must mean the green we're used to is the result from not only green cones activation, but also red and blue cones activation.
My question is: given the current knowledge of cones, the optical nerve and image processing in the brain (or anything else relevent of course), if my blue and red cones suddendly stopped reacting to light, would a 520nm wavelength light look "purer and greener" than it would in a normal situation, or would the brain interpret this as a different "unknown" color? Or perhaps might it not be able to interpet it at all until it forms new connections in order to understand it?
(While this is most likely a hard question to answer, perhaps knowledge about how the brain processes images is advanced enough to form a "likely" hypothesis, which is why I asked.)
