I'm planning to recreate this using a limited palette of primaries much like the Zorn palette. I have titanium white, ivory black, cadmium red, and primary yellow. I'll simplify it in a way that the painting will only capture the big shapes, values and color. Since I'm a beginner, I created color mixing instructions for myself: Light skin tone - Titanium White + Cadmium Red + a touch of Primary Yellow; skin in shadow - Cadmium Red + Ivory Black; muted greens (olive) - Primary Yellow + Ivory Black; Warm tones (orange) - Cadmium Red + Primary Yellow; bluish tint (cool gray) - Ivory Black + Titanium White; desaturated violets - Cadmium Red + Ivory Black; Earth tones (warm neutrals) - All four colors in various small ratios. I know it's not going to look exactly the same. I'd be happy if I can get it somewhere close to a good read.
