WebIt is possible to represent any color in terms of these primaries. They were derived so that equal values of X, Y, and Z produce white. They were arranged so that a single parameter Y determines the luminance of the color. They are related to the sensitivity of the human eye by the use of color matching functions which match to the C.I.E. 1931 ...

To eliminate this variable, the CIE … See more CIE RGB color space The CIE RGB color space is one of many RGB color spaces, distinguished by a particular set of monochromatic (single-wavelength) primary colors. In the 1920s, two independent experiments on … See more The human eye with normal vision has three kinds of cone cells that sense light, having peaks of spectral sensitivity in short ("S", 420 nm – 440 nm), middle ("M", 530 nm – 540 nm), and long ("L", 560 nm – 580 nm) wavelengths. These cone cells underlie human … 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 three-dimensional figure.

Unfortunately I could not find the average age of the observers used to establish the 1931 standard observer (there were 17 of them). But it is known that the average age of the observers used to create the CIE 1964 standard observer is 32 years, see [Pok87].
