In a 1956 article in American Artist, Harry Anderson described how he used an uncommon practice in gouache painting.
He said he used “two different colors on a single bristle brush in painting objects whose color might run from light to dark—as on a cylinder. First I load the brush with the lighter hue and then with a section of the brush I pick up the darker paint so that, when the stroke is made, very interesting accidentals result.”
“This works very well on small objects,” Anderson says. You can see Anderson’s blended-stroke method in the rendering of the bookcase, where each book’s spine was made with a minimum of strokes.
These enlarged details are from the painting “The Widow,” which appears as a double-page spread on page 10-11 of Color and Light: A Guide for the Realist Painter.
