Abandoning Our Values

What makes an object look three-dimensional in a painting or a drawing?

We use a variety of cues to give us this information: light and shadow, contrast, pattern, color, texture, scale, temperature and value, usually in combinations. Our ability to measure these different parameters and make a decision about the dimensionality and location of something in our field of vision is automatic and immediate–a product of millions of years of evolving visual sophistication. Most people do not have to think much about visual perception, but as artists, it is useful to investigate.

When we learn to draw, we practice creating the illusion of form with value changes (light to dark), or chiaroscuro, using all the subtle changes in tone from black to the white of the paper. Having gained proficiency at chiaroscuro work, we quite naturally adapt our knowledge of values to our color work. But the world of colors is not just value-driven, it has an equal partner in color temperature. Temperature (warm to cool) can and does affect our perception of form. As the shape of any object rotates away from the light source, it undergoes a temperature change. It may also display a value change, but not in every case. In the landscape, as an object gets further away, it undergoes a value change and a temperature change as well.

As artists, we can employ temperature changes to our advantage. The Impressionists loved to exploit this effect. Temperature changes in their fine art oil paintings were an essential ingredient in their ability to create scintillating, light-filled canvasses. They thoroughly understood the power of temperature changes within a limited value range in reproducing the effects of sunlight. Cezanne and Monet, especially triumphed at these kinds of techniques, so much so that most people aren't aware of the missing values. See how this black and white of Cezanne's painting above reveals his mastery of temperature within a restricted value range.

In still-life and figurative painting, we can also exploit this concept and make our paintings more effective, and our work easier. The best way to understand and learn how to use temperature instead of value to create the illusion of three dimensions is to set up a simple still life. Join us on The Artist's Road for a more in-depth article and step-by-step demonstrations on how to paint objects using only color temperature changes. If you haven't tried this yourself, you'll be amazed at how effective and fast it is to paint with temperature instead of value changes.

About John Hulsey and Ann Trusty

John Hulsey and his wife, Ann Trusty created the website, The Artist's Road - Painting the World's Beautiful Places.  The Artist's Road inspires with practical art tips and painting techniques for the traveling artist, video painting tutorials and demonstrations, workshop resources, artist profiles and interviews and remarkable painting locations.  The Artist's Road is an artist community for oil, watercolor and pastel artists.  Articles cover intriguing art travel experiences artists have had while painting the world's beautiful places. "I believe I must speak through my art, for the preservation of Nature and the natural landscape from which I take my inspiration and living." John Hulsey is an accomplished artist, author and teacher who has been working professionally for over thirty years. In addition to producing new work for exhibition and teaching workshops, Mr. Hulsey continues to write educational articles about painting for national art magazines, including Watercolor magazine and American Artist Magazine. He has been selected as a "Master Painter of the United States" by International Artist Magazine where his work was previously chosen to be included in the top ten of their international landscape painting competition. He was awarded residencies at Yosemite, Glacier and Rocky Mountain National Parks. "I strive in my art to celebrate the mysteries of Nature - the fleeting light on the landscape, the unimaginable diversity of creatures, the beauty of each leaf and flower." Ann Trusty  is an accomplished third generation artist whose work embodies the natural world and is created through direct observation and translation of her subjects into her paintings. She has found inspiration in the dancing light across the water of the Hudson River (where she had a studio for ten years), as well as the big sky and waving tall grasses of the open plains of the Midwest (her current home). Her work has been exhibited throughout the United States, France and Turkey in both museum and gallery exhibitions, and has been reviewed favorably by the New York Times.
