Interesting Tibit on Shading/Transparency

When shading use a transparent color. To check for transparency of a color....use a newspaper. Swipe your brush across the print with the color you are thinking of using. If it colors the newspaper and you can still read the print..the color is transparent and a good shading color. If you cannot read the print, the color is opaque (contains white) and you would not want to use this color. Thanks Margot Clark for this great information.
