A few years back I took an oil glazing portraiture class using the Anders Zorn Palette - a simple combination of black, white, yellow ochre and cadmium red.  Early this year I did a few acrylic studies of Zorn's work using the same palette. These are not worked up paintings but sketchy, loose impressions done in acrylics.
