Isaac Newton separated light into its components and found my wavelength. The blue range in the coloured light spectrum is between 434.2 nm (blue) and 397.1 nm (ultraviolet)
A cone is a type of light-sensitive cells in the retina of the eye. S-cones (short wavelengths) cover the blue range (at around 420 nanometres) of the visible colour spectrum. The small cones responsible for the perception of emerald green light are relatively new. They came into being relatively late in our evolutionary history, as they did not seem to have had much relevance for our survival before.
