Techniques and Application

Wash

The watercolors were applied as a wash with a Princeton Art and Brush Company 3/4" synthetic sable flat wash brush. The proportion of water to paint was varied for each color to achieve different degrees of opacity. Depending on the strength of the pigment, the ratios of water to paint were different for each color. The following lists the water/paint ratios, measured by weight, used for each color.

Terra Rosa: 30/1, 60/1

Chromium Oxide Green: 15/1, 30/1

Ivory Black: 15/1, 30/1

Overcoat

No varnish or fixative was applied to the watercolor samples.
