589 nm to RGB & Color Calculator
Approximate how 589 nm monochromatic spectral light can be represented in sRGB, and calculate CIE 1931 tristimulus values, THz frequency, and photon energy.
Why You See This Color (589 nm)
At 589 nm, monochromatic electromagnetic waves stimulate Long (L) cones substantially more than Medium (M) cones, while Short (S) cone sensitivity is very low. This biological excitation ratio contributes to the perception of warm amber and orange. Carrying an energy of 2.105 eV per photon at a frequency of 508.985 THz, this spectral line is approximated here with standard sRGB primaries.
