During my freshman year in the York College, Fine Arts Program in 1975 I took a class in Two Dimensional Design. First we studied the rudiments of rhythm, and then we abstracted the underlying design elements of images. The third project was an introduction to color. We used acrylic paint to make color charts of both warm and cool gray scales.
It took a great deal of trial and error to get even steps from white to black and back down the scale again. As a former musician, I used to play my trumpet scales by the hour, much to the chagrin of my family. Trying to get the color scales right in paint is much the same experience, only quieter.
Another part of this Design project had to do with creating these scales in Color. These color scales were placed against various colored backgrounds to demonstrate how different the same colors appeared when imposed on competing ambient hues. These simple exercises introduced me into the world of luminance, saturation and hue, the basic platform of all painters and colorists.
