The yellowish underpainting of Truth (1) was applied by Hodler directly onto the canvas.

This was followed by the flesh tone. (2)
Finally, he underpainted the background with a layer of white. (3)

The blue contour line of the arm (4) overlaps the background at the edge. Hodler then corrected the form of the arm and painted over the contour line again using the light shade of the background (5).

He made later corrections using Raffaëlli sticks (6), so establishing the definitive form of the figure.
