Softlight Layer System

My study for the day, the "Softlight layer system" in shading skin tones.
I was thinking about whether this is imaginable in any case, on the grounds that typically a few artists utilize the overlay or color system.
For me I begin painting in grayscale mode to clean the values of the picture then apply hues directly after.
So I think its possible to depend just in soft light since it's kinda bothering to change diverse layer modes every time.
