Why You See This Color (616 nm)

At 616 nm, monochromatic electromagnetic waves activate Long (L) cones substantially more than Medium (M) cones, with zero S-cone stimulation. This specific biological excitation ratio is processed by retinal ganglion cells as warm amber and orange. Carrying an energy of 2.013 eV per photon at a frequency of 486.676 THz, this spectral line is reconstructed via standard D65 gamma-corrected sRGB primaries.
