Burnt sienna toned ground, then a palette of burnt sienna, lead white, ultramarine blue, yellow ochre, and burnt umber. I really liked this palette (though it was strange to have burnt sienna as one's only "red"), and only barely began to discover all the different subtle combinations that can be created. Very happy with how this turned out. This was about 2 hours, alla prima with a mirror.
I have to figure out a better setup, though... I can't seem to manage a way, yet, to have the spotlight (and it's awfully hot under that thing; artists' models, I empathize!) on my face without it being either in my eyes or too bright on my canvas, or both.
Also, I'm a bit bummed that alla prima self-portraits are pretty much limited to the straight-on view. Unless I'm majorly misunderstanding something or there are some tricks using multiple mirrors, there's no way to paint one's own profile (for example) alla prima...no?
