This summer, on one of thoses numerous windy and rainy days we had at the Lake, I borrowed
a book of Betty Edwards,(I had already read The new drawing on the right side of the brain, and I've loved it);this one is called COLOR, A course in mastering the Art of mixing colors.
One of the first exercises was to make our own color wheel, mixing colors.
I made 6!(not the same, of course) it was very useful to paint it,it helped me to remember the primary, secondary, complementaries colors. I had already learned that thousands times,without remembering very clearly, but the fact of drawing ,painting,cutting(with a plate as a template) looking for the colors , and placing that on a clock change everything.
