"Regarding Imprimatura"
by CHERYL KLINE
"Imprimatura" also known as: "First paint layer" dates
back to the middle ages and became a common practice during the
Renaissance. Most artists today simply call this "toning your canvas."
I
tone my canvas because I want to get rid of the pure, white of my
surface. I cannot compete with this intense white especially when I am
trying to establish values.
When
instructors tell you to "tone your canvas," ask them what color. Make
sure that you merely stain the canvas and do not apply it so thick that
it is no longer transparent, you actually want a wash of tone to see
through to the canvas or board. It will usually be a medium value
meaning in the middle of the value scale, not too light and not too
dark.
Since
I paint in oil, I will tone my canvas in oil paint if I have an extra
day for it to dry completely before using it. Or, I can thin the paint
with mineral spirits and let it dry in the sun for about 1 hour. Otherwise
if I am in a hurry, I tone my canvas with acrylic paint and set in the
sun to dry for 10 minutes. I actually like the "tooth" that an acrylic
ground gives the surface to work on. Just make sure that if you do use
acrylic as your Imprematura that your surface was not gessoed in an oil
based ground otherwise the acrylic will bead up and not penetrate the
surface.
A grey toned canvas will
give you a cooler, neutral tone to work on. This is one that I prefer
to use when I paint portraits. Allowing this first paint layer to show
through the other layers of paint adds depth to the shadows and middle
tones.
Burnt Umber and Thalo Blue |
Another warmer mixture is Burnt Umber and Thalo Blue. Sounds
crazy but if you use just a bit of the blue with the Burnt Umber, you
get a greenish, warm brown. Rub it in to reveal the weave of the canvas
or the board surface and you'll have a nice ground to paint on.
Raw Sienna or Yellow Ochre with a hint of Ivory Black makes an excellent neutral sandy tone. This is one I like for plein air painting and if you save some of the color to show through subsequent layers, it makes a nice glow around the objects.
Venetian Red or any of the earth reds like Sinopia or Red Ochre are
more difficult to navigate. The red is so intense that you will be
fighting the color in the first stages of painting. However, having bits
of red showing through or under a green or blue can be really
exciting.
Before you choose the color for your underpainting, ask yourself if you want this color to show through the other layers and if so, do you want a warm tone or a cool tone. Toning the canvas is a great way to "warm up" getting started and to not be intimidated by the virgin, white canvas in front of you.
