Introduction to Oil Painting #5: Tetradic Color Notes


We focus on brushwork and not mixing colors. These approaches bring awareness to how brushwork can work for the painter and to the use of temperature to create contrast and spacial depth on the picture plane.

Examples: Impressionism, Post Impressionism, Fauvism.


Manet: Notice length and strength of strokes.


Van Gogh: Notice abrupt changes in temperature. See how hue and brushstroke are related. Notice the difference in the brushwork. See flat and round brushstokes.


Matisse: Each color/value a deliberate stroke. Each plane delegated a warm or cool temperature. Also, notice how brushstrokes are layered over each other from the back to the front of the form.

And now, our in class assignment. Our key is determined by an orange fruit.


We are working with a tetrad harmony. Here see red, orange, blue and green. Our mixing is limited to expanding the value range of each hue with white and black (ivory). Remember, we are not mixing these hues together.




Brushwork and color note demo. When you place one stroke stop to evaluate your next color note. It maybe somewhere you did not expect it to be.
