Why You See This Color (467 nm)

At 467 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 641.954 THz and photon energy of 2.655 eV, this wavelength is converted into sRGB coordinates by projecting its spectral chromaticity point onto the CIE 1931 standard observer locus.
