Why You See This Color (600 nm)

At 600 nm, monochromatic electromagnetic waves stimulate Long (L) cones substantially more than Medium (M) cones, while Short (S) cone sensitivity is very low. This biological excitation ratio contributes to the perception of warm amber and orange. Carrying an energy of 2.066 eV per photon at a frequency of 499.654 THz, this spectral line is approximated here with standard sRGB primaries.
