wolf kahn, gray, restraint and clouds

These three cloud studies began with layers of gray. I held back my color (sort of like holding my breath) till the end.  When I exhaled I just allowed a very small amount of saturated color. Temporary loss of freedom made me think differently. It was worth the  restraint.
Wolf Kahn once said that he would ask the participants in his workshops to make a bright painting that celebrates the color gray. He felt it made them think more deeply about the variety of ways gray can function in pictorial space. WK actually went through a period of time when he pretty much only painted in grays.
I don't know if I can go that far, but I can celebrate gray.
