Two skin gradients I use when I render a drawing from Black & White to Color, to avoid that muddy look on the skin from just using blending modes like overlay and color directly.
- When you have your BnW drawing, use the correction layer Gradient Map, and in Color Blending Mode. I suggest using a mask to cover only the skin.


- Try between the two skin gradients

- You can leave it like that, but I suggest trying some color variation in a new layer. Soft Light works for me.
