7.5x11 watercolor using all the blues in my palette: UB, Prussian, Midnight, cobalt, cobalt teal blue, Antwerp, manganese, peacock, ultramarine turquoise, periwinkle, cerulean, verditer, moonglow and carbazole violet. I used a black and white printed ref courtesy WetCanvas Weekend Drawing Event (Li Newton). The challenge was to use only blues. Later I might go back into this with golds and yellows to warm up this island beach scene. Support: Fabriano 140 lb rough paper.
