The X-radiograph
reveals that the white paint for the collar
extends under the area that is now black.
While still wet, the lead white paint
was manipulated with a palette knife
or with the back of a brush.
The paint was pushed away and accumulated in ridges, which absorb the X-rays and are thus visible in the X-radiograph.These ridges are visible on the paint surface as white lines on dark paint, and imitate the texture of fabric. They are not painted on top of the black, but protrude above the dark paint film.
