Paul Bril occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature reads distinctly warm: the reds and earth tones from Paul Bril carry the compositional weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A28C48 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.0%). 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 4 of Paul Bril's sequence - a single chapter in a chromatic story told across many works.
