After - Warm over Light --the background receded and enhanced the flowers
After re-reading Tom Buechner's book, How I Paint, I decided to repaint the background of this painting to test what he says:
"All colors look cool over dark, even red and yellow: all colors look warm over light, even blue. It is the secret of the old masters, maybe the most important thing in this book."
Before - background was cool blues, purples, pinks and somewhat chalky
I don't think I did it correctly, but what I did do definitely helped the painting. I will continue to experiment with this principle until I really understand it well.
