I don't understand how we see violet. We have cones sensitive to red, blue and green and so can see these primary colours. Colours with wavelengths between these are seen when more than one cone is stimulated. How can we see a colour of shorter wavelength than blue? Surely it ought to stimulate the blue-sensitive cone only and therefore be seen as blue. Can anyone help?
