burnt sienna too. I didn't use any earth colors in the skin tone for this painting. Hardly any red or blue either. Instead, I shifted to prismatic, more secondary colors. Light side flesh was mixed from yellow and magenta. Shadow flesh was cooled and shaded with viridian and cerulean blue. Sienna and umber browns were replaced with mixtures of perinone orange, viridian, and alizarin crimson. Getting away from earth colors and instead using high chroma dye-based pigments gives more color space for scarlets, mauves, violets and greens to model volumes. I didn't pull it off so well in this painting, but I think this is the way to go.
I started with a high contrast two value block-in and any features in partial shade, like the eyes, were painted as a simple dark mass. I did this more for positioning than to depict appearance. I need to remember to add some construction lines and double-check proportions at this point, then lift out detailing.
Also, I thinned the Galkyd underpainting with Turpentoid so it went on thinner and looser. As it set, I found I could brush on skin modeling with hog-bristle brights and paint straight from the tube, just like canvas. Top coats, I used a linseed/stand oil/Gamsol mixture. I took a photo of the model, so I'll see if I can clean this up a bit and re-post. 16" x 14" - 3 hours.
