Actually there are slight variations in the wavelengths to which the 
rods react; some women even have two different receptors for red-ish 
wavelengths (in addition to the blue and green receptors), making them 
particularly good at discerning color differences (ironically their male 
children have a higher risk of being born red-green color blind).
