Pastel by its nature facilitates a spontaneous application of color. Being a dry medium, mixing is achieved by layering one color over another. This dry mixing is incapable of duplicating the subtlety and variety of wet paint. For this reason an assortment of individual
colors, chromas and values are needed. Otherwise we’re limited in
our ability to accomplish the full spectrum of other art media.
As pastel artists, it’s in our best interest to acquire knowledge of
how colors interact when mixed. The first step in gaining color
confidence is to develop an understanding of the color wheel. It shows the relationship of individual colors derived from light (Sir Isaac Newton
in the 17th century proved scientifically that light held the full
spectrum of color). Today there are two common wheels in use: the
“Triadic,” which consists of three primary colors, and the “Munsell,” which
consists of five (I’ll discuss in-depth their individual
characteristics in next week’s post). A few of the relationships we need to understand are: analogous, complementary, split complement, and discordant. Having an understanding of these and how they create different effects in our paintings will help us to better control the
appearance of color and create color harmony in our paintings.
Even if you never plan on painting with anything but pastel, it’s advisable to experiment with wet paint. As any wet media artist can
attest, learning how to mix individual hues to arrive at specific tones takes trial and error. Individual pigments have their own personalities and, when mixed with others, often lead to exciting outcomes. If you’ve never worked with a wet medium, I recommend oil. It stays wet and allows for prolonged mixing and experimenting. Buy a
minimum of four tubes: yellow (cadmium yellow light), red (cadmium red
or napthol red), blue (ultramarine blue), and white (titanium or a
mixed white). Other combinations may be used, but these colors work well and are readily available at most art supply stores. Place them on a palette; glass works well and is easily cleaned. Then, experiment—play and mix with abandon, taking note of the effects. Over time you’ll become more comfortable with the characteristics of color,
leading to a stronger intuitive response when next you work with dry
pastels.
In the photo above, I’ve arranged mixed colors that represent the color wheel on a glass palette. I mixed them all using one yellow, red and blue. I added white around the perimeter and colors were mixed across the wheel
in increments to show the natural graying of complementary colors.
