One of the more overlooked technical devices in creating a painting with sophisticated interest, is gradation. Although it is easy to think of gradation in terms of color or value, by extending your gradation vocabulary in all aspects of the work you can add interest, excitement, passive and active passages, elicit specific responses from viewers of the art, and produce paintings that invoke mood, time, and feeling in a more calculated way.
COLOR AND VALUE
Before we look at more advanced ideas, let’s look at a few common examples of using gradated color and/or value in the landscape. If you paint landscapes, you may have been taught to apply gradation of lighter to darker or warmer to cooler in a large expansive sky. Not being one to fall back on formulas, I suggest my students begin to recognize when this truly happens in nature, at what times of day and with which specific colors and values rather than automatically reverting to this concept in every single case. Sometimes the sky may also gradate from warm to cool (or vice versa) as it spans from left to right rather than from horizon to Zenith. Learning which of these devices to use to convey a specific idea can strengthen your landscapes and keep them from all looking the same.
Gradation of color and value can also be useful when painting other subjects. In a still life, for example, you might use a gradation in the background from left to right and from top to bottom. Notice in this quick head sketch how color gradates and alternates from warm to cool to warm to cool to warm to cool as it wraps around the form of the form.

Still another way to think of using gradation with color, is by varying the amount of color intensity from very neutral to extremely chromatic. Notice here, from left to right, we experience neutral, chroma, less chroma, neutral. See how the most intense chroma is where I want you to linger the longest when you look at the painting. I use this same type of gradation many times in the landscape to move the viewer’s eye around the painting, lend atmospheric perspective, and add interest.

SHAPE, LINE, EDGE, and TEXTURE
Now, let’s take a look at gradation and how it can be useful in reference to other technical aspects of painting.

In this same painting, notice how the edges are gradated. See how they are much sharper and harder in the most important parts of the painting, and gradually become lost and soft as they radiate away from them.

Practice seeing and using gradation as many ways as you can. Then edit and use the types that work best for your subject. This sort of experimentation brings a load of learning at the easel and buzz and excitement to your next exhibition.













Here’s how you prepare your canvas: It’s easier to work on a tabletop for this than using an easel. Tape the canvas to a board to allow yourself freedom to spin the chart around as you fill the squares. Measure out a quarter of an inch for the width of the tape, then an inch for each square, and repeat for every color. Make tic marks with your pencil, rather than lines, to indicate placement. Put the quarter-inch tape between the marks and leave a tag hanging off the end for you to pull when you’re done. Place all vertical tapes first, followed by all horizontal tapes. You will carefully remove the tape as soon as you are done with each chart (don’t wait till later!); it is easy to pull the horizontals off first, then the verticals. Now write the initials of the colors you will be charting. For example, the colors I use for the limited palette are Transparent Oxide Brown, Ultramarine Blue, Cadmium Red, and Cadmium Yellow Pale: TOB, U, CR, and CY. The Transparent Oxide Brown chart will have these headings on the columns: TOB, TOB/U, TOB/CR, and TOB/CY. Note that the size of your chart/canvas will be determined by the numbers of colors and values you want to explore. For the limited palette, I chose four colors and five value steps, so I will have four across and five down, plus some space between each chart. Measure it out accordingly.
Here’s how you create your chart: Understand that this is an exercise for your eyes, mind, body, and soul. It will demand your full involvement in a most personal way as you begin a real dialog with your colors. Give yourself lots of latitude, grace, and hours.
When you have your first and last colors laid in, you will mix the value that is right in the middle of those two. Mix it and hold it on your knife over the two color values on your chart and ask yourself which it favors more, the pure color or the lightest tint. This is when your colors really start talking to you. When you finally mix a color value that favors neither, you have your middle square. The last two colors are halfway between each of these: one is halfway between pure color and middle color value, the other is between middle color value and lightest possible value.
It’s easy to see how your mind and eyes are challenged by the creation of color charts, as all the measuring is intellectual and visual. If you try to literally measure part-for-part, you will not have an accurate chart because every pigment has a different saturating power. So, your mind and eyes are about to get smarter. You will not find how it challenges your body until you start the process. You will then be amazed at how physically demanding this assignment is. This isn’t for sissies. And as for the soul… ultimately your choices, as objective as this process seems, will be determined by how you feel. It can’t be taught. You will only get it when you do it. This is why charts must be done and not just seen. It’s also why the color charts vary between different artists, and why Richard Schmid can say that he learns something new every time he makes a new set. He is still making new charts for himself! And since he’s been painting longer than a lot of us have been breathing, perhaps it really is a worthwhile thing to try.
