The most sensitive pigment, rhodopsin, has a peak response at 500 nm.Small changes to the genes coding for this protein can tweak the peak response by a few nm;pigments in the lens can also filter incoming light, changing the peak response.Many organisms are unable to discriminate between colours, seeing instead in shades of grey; colour vision necessitates a range of pigment cells which are primarily sensitive to smaller ranges of the spectrum.
