540 nm to RGB & Color Calculator
Convert 540 nm monochromatic spectral light into exact digital sRGB, CIE 1931 tristimulus XYZ coordinates, THz frequency, and photon energy.
Why You See This Color (540 nm)
At 540 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 (555.171 THz, 2.296 eV) as brilliant emerald green to chartreuse, mapped here to digital sRGB gamut coordinates.
