Why You See This Color (460 nm)

At 460 nm, incoming photons stimulate both Short (S) and Medium (M) cone opsins simultaneously. The visual cortex compares the differential ratio between S-cone and M-cone activation, synthesizing the vibrant perception of cyan and sky blue. With an oscillation frequency of 651.723 THz and photon energy of 2.695 eV, this wavelength is converted into sRGB coordinates by projecting its spectral chromaticity point onto the CIE 1931 standard observer locus.
