To investigate the needs and benefits of introducing the cone-fundamental-based spectral luminous efficiency functions (and the color-matching functions) defined in CIE 170-2:2015 into the SI photometric quantities, and if appropriate, to propose approaches and strategies for introducing the cone-fundamental-based functions and resulting photometric quantities (and basic colorimetric quantities) in the SI.
