You can use camera neutral as a starting point. eric Chan has publisched a version 3 beta of some nikons ( d3 and d700 i believe), which i prefer actually. I use D700 . For fashion, beauty and portraits is shoot in studio conditions and always make a camera profile using xrite color checker passport and DNG Profile Editor from Adobe labs. Reason is color correctness and saturation, also use it for color balance with setting color temperature.
If properly executed it is all about using the cameraprofile, setting the color temp and whitepoint and black point, and color wise you are done. Other settings as tone curve, sharpening, lens corrections need to be done, but have little to do with color.
