There are a number of underpainting techniques that I enjoy using with my oil pastel paintings: watercolor or soft pastel washes (washed with either water or alcohol), and gouache – acrylic – oil thinned paint. Each offer a different result and are used for a variety of purposes.
But today I decided to use a watercolor wash for three studies of underpainting colors to see the overall effect on a landscape scene that I plan to paint in a larger size using one of these techniques. The scene is 2/3rds clouds and the rest is land. What follows is the study for each technique w/a corresponding painting study for each using Cotsman Watercolor Paper. Click onto the images to increase the size.
Which style appeals the most to you?
Complementary (using opposite color on color wheel from natural color): (9 x .45)
Analagous (using color next to natural color on color wheel): (9 x 4)
Monochromatic (using one color): Blue (9 x 4.5)
