That is interesting. The method I described is hardly new. It was defined completely, along with the rest of the CIE XYZ color space, by Wright and Guild in 1931 and is used extensively in color science. Anyone with a basic background in color science would have knowledge of this, especially today, as it is a critical part of digital color management.
Mustafa, if you are interested in learning more about color science you may find Principles of Color Technology by Roy Berns a helpful resource.
