Though the skies directly ahead are dark in this small painting by Brazilian painter Lucas Arruda at David Zwirner Gallery, light shines out from behind the clouds, ready to transform the scene. Light conditions and colors vary greatly in Arruda’s signature seascapes and jungle-scenes in response to time of day and atmospheric conditions yet each painting draws viewers in to appreciate the particular, fleeting circumstances presented. Titled ‘Assum Preto’ after a Brazilian bird whose song alters in response to light, this show’s sensitivity to time and place is so subtle and calming as to be therapeutic. (On view through June 15th in Chelsea).
