August Macke, "Self-Portrait With Hat"

August Macke, Self-Portrait With Hat, 1909; Kunstmuseum Bonn.

Modern portraiture, even when somewhat abstract in composition, tends to retain many naturalistic traits, such as flesh coloring, arrangement of facial features, and so on. A tinted appearance in a portrait, such as the yellowish overtones in the altered Macke image below, usually indicates a poor copy — either a digitally altered image or an inferior onsite photo. The picture above, from the Kunstmuseum Bonn, provides a better look at Macke's Self-Portrait With Hat, retaining much more of the detail, depth, variation and emotion of the original.
