We are working with a still life where the objects are different colors. We choose a tetrad containing at least two observed local colors. In this case yellow-orange and yellow-green.
Build a grid showing the mixing potential of the tetrad.
Make a light line drawing of objects. Make sure there are plenty of overlapping shapes and foreshortening. Choose tints, tones and shades of your 4 hues.
Start the drawing with the 4 pure hues first. Work the entire surface. Begin to mix the 4 hues, then increase your palette with tints, tones and shades.
As you build up the drawing you will have a better idea of where to put tints, tones and shades. Erase if necessary but try to avoid using a subtractive technique with colored pencil.
Pay close attention to shifts in value and temperature.
Increase pressure towards the end of the study. At this point you’ll know where to do this-especially after 1-2 hours of focused observation and decision making.
