This is painting wet into wet and into drying acrylics, impasto technique.
I only used two colors for the face.  The cool neutral set of Ultramarine Blue and Red Oxide. 
Back in the 1200's when they started painting again after the wars. No one was able to afford the luxury of the color ultamarine blue, instead artists used a translucent blue green earth oxide and opaque red earth oxide to under paint with. 

Burnt Sienna warmed my picture where necessary as a glaze. That's it, no Naples Yellow this time.
