The color scheme in The Death of Marat consists mostly of neutral hues like the whites of the turban, cloth, paper, and quills, the green of the cloth over the bath, the brown from the wooden crate, and flesh tone of Marat’s skin.
There are a variety of implied lines created by the subject matter leading us (the viewers) to gaze around the composition, with a specific focus on Marat and the knife on the floor. For example, the vertical lines from the folds of the white and green cloth near Marat’s hanging arm.
Space is composed of the main subject matter in the foreground, more specifically in what is called the “shallow” foreground. The background is neutral and in a dark hue, which creates a backdrop effect for the figure in the foreground.
Jacques-Louis David created a naturalistic composition in terms of form, in other words, the figure of Marat is depicted in a realistic manner and muscularly defined, as was also characteristic of Neoclassical paintings of the time.
