Diebenkorn's Ocean Park series, begun in 1967, makes general reference to the beachside land- and cityscape of the neighborhood in Santa Monica, California, around the artist's studio. The series is the work of an artist who synthesized the principal currents of the twentieth century's most rigorous abstract art (after painting representationally), joined it to a painterly 1950s sensibility, and created a new style with both the seriousness and the decorativeness of his exemplars, and with a gentle but firm sensuousness that is entirely his own. The work uses the components of Piet Mondrian's mature art, but escapes from the form of geometry that Mondrian had adapted from Cubism to learn more from the less confining structures, and the breathing surfaces, of Barnett Newman and Mark Rothko. But Diebenkorn recomplicates the spareness of those artists' fields, reintroducing a searching, durational record of the work's creation.
The influence of another touchstone for Diebenkorn, Henri Matisse, is apparent in Ocean Park 115, as in the rest of the series, in the way the space is divided into flat planes and bands of color. Built up of successive layers of pigment, the painting's blues and greens shift in their density, invoking a translucent luminosity.
