Why You See This Color (522 nm)

At 522 nm, the radiation strikes the human retina close to the peak photopic sensitivity curve V(λ) (555 nm). Both M-cones (chlorolabe) and L-cones (erythrolabe) are strongly depolarized, maximizing luminous efficacy per watt of optical power. The visual system perceives this radiant energy (574.315 THz, 2.375 eV) as brilliant emerald green to chartreuse, mapped here to digital sRGB gamut coordinates.
