The most common mistake at deeper values is darkening with black, which flattens the warmth and richness that makes deep skin tones read as alive rather than muddy. A dark red-brown (burnt umber or Van Dyke brown) with a touch of a warm red keeps the color rich as it darkens. Adding white to create highlights should shift the whole mix warmer, not just lighter, or the highlight looks chalky and disconnected from the rest of the skin.
