Welcome Back Cobalt

Welcome Back Cobalt.  Watercolor and Crayon.
Approximately 4 inches square.

I haven't used cobalt in a long time, and I'd forgotten how much I like the way it granulates in washes (see the sky), or can be used as an almost opaque color (see the foreground),  Nice.

Indian yellow, prussian blue, cobalt blue, and quin violet.  Plus some crayon.  On a scrap of paper, which is probably 300 lb Kilimanjaro.
