Totally with Rick on these point...

When using LUTs, I always grade with the out as the last node in the workflow, and at least one or two adjustment nodes before it. There are cases when fine adjustment needs to follow the LUT node, but this is the exception than the rule in my workflow.

In other lighting situations, having the face in green and dark grey can also work. It depends on what you’re shooting and the intents of the director who may want a Christmas romance look or a disturbing thriller.
Going with pink, grey, or green on skin tones depends on your interpretation of the scene and the lighting thereof and they are pretty safe as skin false color.
