### Notes

CIE (1931) *x, y* chromaticity space showing the spectrum locus (continuous line) and spectral wavelengths at every 10 nm (filled circles). A representation of the color of each coordinate is shown, which is necessarily very approximate, since it is impossible to reproduce
spectral lights in print.. For more details see here.
