"If you slightly squint your eyes, you will see
that at least 2 and
possibly 3 values of color
make up any object in the natural world.
Practice creating entire paintings with
no more than 3 values on any
object.
Paint a few of those and you'll discern a rhythm
between areas of 1, 2 and 3 values. It's a fun game."
