How do I calculate the chromaticity coordinates of a single wavelength of light?
To compute the chromaticity coordinates for a monochromatic stimulus (a single wavelength, wl), simply read the values of the color matching functions (x-bar, y-bar, and z-bar) and do the following computation: x = x-bar(wl)/(x-bar(wl)+y-bar(wl)+z-bar(wl)) y= y-bar(wl)/(x-bar(wl)+y-bar(wl)+z-bar(wl))
