So -- with the prospect of replacing all that paint looming over me, I'm thinking about my palette again (trying not to think about the cost!). I've become very reliant on a Gamblin color bizarrely named "caucasian flesh tone" which is a nice warm peach, like naples yellow touched with rose. I rarely use it for faces, but it works well as a light in a mostly blue painting, the way that naples yellow shines a light in purple ones. Maybe it's time to get rid of it... or try to mix up some new approaches to color. Keep posted.
