A few notes before you start painting:
Mondrian used strips of transparent paper to determine where he wanted to draw his lines. Then he drew the composition onto a stretched, primed canvas with charcoal and a ruler. He was looking for asymmetrical balance. The color was secondary. He sometimes let others choose where the blocks of color would be, but they were always primary colors. Later, he used colored tape to decide where he would paint colored lines and color blocks. He also painted over portions if he changed his mind about the composition, color or width of the line. The black lines were painted thinly. The white and colored areas have a heavier build-up of paint. The white areas are generally not stark white. They look light blue or grey. Some think this may be from changing the underdrawing so many times. Also, the primary colors are more complex than they may seem. For example, Mondrian used different reds (some were more opaque than others) to achieve the color value he wanted. Here we go! Have fun!
