You peer and peer, and from the brown background emerges a brown garment, relieved by the black cap, and the black cloak that falls over his left shoulder.

Luminous black and luminous brown! Brown is the side of the face in shadow, brown is the brow in shadow.

All is tributary to the glory of the golden brown on the lighted portion of the face.

The portrait composes into a perfect whole.
