The most chromatic and the most unusual of all the life drawings — a seated figure rendered entirely in blue watercolor rather than any drawing medium. The figure is described in two blues: a darker, more saturated blue for the main contours and shadow zones, and a lighter, more transparent blue for the form's interior wash. The paper shows through at the lightest zones, the white creating the figure's highlights.
This is not a drawing with color added but a painting — the figure described entirely through the watercolor wash, no pencil or ink line underneath, the contours created by the edge of the wash rather than by a separate drawn line. The technique connects this figure to the fluid watercolor approach of the landscape works rather than to the precise line drawings of the life drawing series.
The figure is complete and energetically posed: a seated woman in three-quarter profile, one knee drawn up, the other leg extended to the lower left, the upper body slightly leaning. The feet — both visible, described with the characteristic Cothran toe-by-toe attention — are the most carefully detailed zone. The face in profile shows the most abbreviated description: the nose, the brow line, a suggestion of the eye.
The blue-on-white gives the work a quality of Mediterranean light or studio daylight — the figure exists in air rather than in shadow. This is the most purely optical of the life drawings, the figure understood as colored light rather than as line and tone.
