Francis Barlow occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The most saturated colour, #E0B189, is reserved to 3.8% of the surface, where it acts as a focal punctuation. 54 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The palette is recognisably Francis Barlow's own: particular in its temperature, chroma, and the economy of its brightest note.
