It's probably good to start with XYZ, but we have much better colorspaces now that do a better job at correlating with our vision.
Mainly CIE 1976 L',u',v' and even more recently ICtCp from Dolby research.

These features are not really replicable in any other colour space, at best you can use a linear transformation of it (which XYZ already is, and it has almost all properties you could want of a choice of basis).
