CMC and CIE ΔE94 color difference values are computed from the CIELAB values you mentioned. The FMC2 color difference equation pre-dates the CIELAB color space and is based on earlier CIE colorimetric coordinates. I would recommend the texts “Principles of Color Technology, 3rd Ed.” by Berns and “The Measurement of Appearance, 2nd Ed.” by Hunter and Harold as good places to learn more about the history of these equations and the equations used for computation.
