Depending on the way the canvas is lit, some elements of the painting "WTC Day" (as the towers, or the sculpture "Crown of Beams" on the groundfloor), change in appearance by virtue of the different pigments used here.
Some zones in the painting treated with these pigments reflect light.
Colors and materials therefore change in appearance, depending on the viewer's movement in relation to
to the canvas' still position.
See photo of the same painting on next page, with lighting oriented differently on the canvas.
