I love the contrained palette Wyeth used in this painting. I look and see three colors.Titanium White; Burnt Umber, and Payne's Grey. I hope mixed media means "whatever works", because that is what I do.
I spent part of my life near the Wyeth home in Pennsylvania, and though I remember many trips to the Brandywine Museum, I don't remember seeing many Wyeths. Which is a complete and total shame.
Three generations of painters. Imagine, for one, just having that kind of support for your career choice within your own family.
