Watercolor Koi beneath Willow Branches

Purist watercolorists use no white paint at all. Any white, like the pale patches on a koi, is bare paper left alone while the washes go on around it, so the light parts have to be planned before the first brushstroke. Under trailing willow branches the fish turn through clear green water past mossy stones. The paper grain shows through every wash in this watercolor koi jigsaw puzzle.
