Robert Henri sits in the centre of the value range, lending the palette a sense of even, sustained light. 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 saturated accent, #B56746, registers at 3.6% - sparse enough to feel like a deliberate surprise. The full value range is 60 units: broad enough to build convincing three-dimensional form. Palette 13 sits within the larger chromatic argument that Robert Henri's complete body of work advances.
