All corresponding values have been calculated from experimentally obtained data using interpolation. The standard observer is characterized by three color matching functions. See more The CIE 1931 color spaces are the first defined quantitative links between distributions of wavelengths in the electromagnetic visible spectrum, and physiologically perceived colors in human color vision. … See more In the CIE 1931 model, Y is the luminance, Z is quasi-equal to blue (of CIE RGB), and X is a mix of the three CIE RGB curves chosen to be nonnegative (see § Definition of the CIE XYZ color space). Setting Y as luminance has the useful result that for any given Y value, … See more Since the human eye has three types of color sensors that respond to different ranges of wavelengths, a full plot of all visible colors is a … See more A few other XYZ-style color-matching functions have been available.
