The color accent of the painting is on the dark and light blue tone. It can be seen in the sky, the water, and a part of the embankment. Ships decorated with flags enliven this blue background and make the port look festive. Dufy paints contours of houses, the pointed cathedral on the shore, and ships on the water in thin, light black brush strokes. He turns the objects into an ornament, and the boundaries of color and contours often do not coincide.

In Dufy’s works, color goes outside the lines. The artist once noticed that the human eye sees color first and then the contour. Using his observations, Dufy gave color a distinguished independence. The combination of decorative color with the quick and light drawing gives this painting a sense of space and moving humid air.
