The All-Important Underpainting
h e nice thing about oils is that they’re wet;
the problem with oils is that they’re wet. h at’s
why I like to start my paintings with a fast-
drying, transparent underpainting in warm
and cool colors. h e type of medium I use
depends on the size of the painting. If it’s
18x24 or smaller, I create a 50-50 mixture of
paint and Gamblin Gamsol and literally scrub
it on as if I were cleaning my brush. h e color
gets thinner, more luminous and transparent,
and the paint dries quickly.
On the other hand, if my painting is larger
than 18x24, I add a second layer of a dif erent
consistency to my underpainting. I follow the
scrubbed-on layer with a wash, the dif erence
being that I dilute my paint with more Gamsol
and, using a two-inch brush, cover the canvas,
applying the paint with both a sense of aban-
don and an intuitive feeling for what’s needed.
h e visual ef ect of this application is more like
a watercolor wash and, as with watercolor, the
“accidents” of unexpected drippings occur. I
value these unplanned marks, for they add to
the overall texture of the underpainting and
quite possibly will add mystery to the i nished
work and bring pleasure to the eye.
h e underpainting literally sets the tone
of the work. I use a mixture of Winsor &
Newton burnt sienna (a warm color) and any
brand of ultramarine blue (a cool color) to
make a special “black.” Adjusting this mixture
gives me dark colors, both warm and cool,
