Painting My World: More from the Paint-out...Purple Irises pastels - Karen Margulis http://kemstudios.blogspot.com/2011/05/more-from-paint-outpurple-irises.html <lovely explanation of "dancing with the underpainting">
These elegant Irises were created by fine artist Shadia Zayed. She began with a background surface in shimmering metallics. The simple underpainting of the iris was then outlined in strong gestural black lines. Finally, Shadia used hand painted found collage papers and tissues to collage the surface of the iris and a portion of the background. The result is a simple yet dynamic painting in complementary hues of purple and yellow, with subtle texture and pattern.
