Now here's a study in low contrast. [Please do NOT
ask me why I'm in this lingering PINK phase. I don't even really
LIKE Pink!] All the colors around the dark pins were drawn from the
"focus fabric"...and even though this has no contrast to
speak of...I still kind of like it...or...
To get more pronounced pinwheels, you might choose
to use two very contrasting colors for the pins, against a white
ground...
