“I love using watercolors to paint trees,” Nicolas Party has said. “The water creates natural movement that forms shapes on the paper. You don’t really control how the liquid moves on the paper. You have to let the fluid element of the paint do its part—the painting is moving and alive for several seconds.” Party presents 11 new watercolors in this online exhibition “Trees,” works that pay homage to the will of the water and the power in the colors. —E.C.
