"WebApr 24, 2024 · Perhaps the most well-known chromaticity diagram is the CIE 1931 Chromaticity Diagram. It’s plotted using x,y coordinates. The horse-shoe shaped border is created by plotting the chromaticity of each individual wavelength of the visible spectrum. Called the spectrum locus, this is where pure hues at full saturation are found. " - Chromaticity and luminance diagrams
