I recently took a class with Jerry Thomas called French Impressionist Blue Painting. The basic premise is that you use at least 2 or more pigment blues, and keep them isolated
from each other in different areas of your painting.
This particular scene is at Creve Coeur Lake in St Louis Missouri. My husband, sons, and I have spent lots of time sailing here during summers. I used cobalt blue for the sky, Prussian blue for the water, and ultramarine blue for the snow shadows. Blue is a space color, and there is a strong sense of space in this piece. I started with a panel toned in bright yellow, to offset all the blues and warm it up, so it wouldn’t look icy cold. I also used soft pinks, yellows, and violets in the grays of the trees and shrubs.
