In this step, I define the South Rim,
which is about 1000 feet lower than the North Rim, so actually you are
able to see some of the landscape behind the Canyon Rim. I try not to
put too much detail in the Rim, as it would only distract from where I
want the eye to go. The correct color, combined with soft edges should
make the distance believable to the eye pretty much by itself. When
mixing colors, values change. The more colors are mixed together, the
weaker the color value becomes. Until you reach a warm, dirty gray.
Mixed colors will appear further away in a painting than, for instance,
a primary color, which will jump to the foreground.
In addition, in this step, I’m
starting to add some cooler colors, like the greens, in the valleys
below, on the right side.
