Why You See This Color (510 nm)

At 510 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 (587.828 THz, 2.431 eV) as brilliant emerald green to chartreuse, mapped here to digital sRGB gamut coordinates.
