This is a class demonstration I created in the first year of my school in 1998. I did it in the Visual Development class. Students were a bit baffled when I worked up the color version of this design. I started with a gray marker rendering of the composition. Afterwards I made a photocopy of the toned design and used color markers to bring the xeroxed image to full life. Helped to drive home the point that gray tones and color are strongly related to each other. You're in greater command of color when you learn to use your gray tones effectively.
