I am continually being challenged with the loss of my vision. I change my medium to keep painting. And I love it when a painting comes together.Using complentary colors to make a painting pop. It makes me hppy. Painting is good for the spirit, mind and soul. Having lost most of my color I will start with a white canvas. Then add black with a palette knife to get the shapes I want. Then add color.  Having painted most of my life I know which colors to mix to hepefully get the desired result.
