The value structure of Marsden Hartley is mid-key: quiet, controlled, and cohesive. Warm hues command this palette; Marsden Hartley favours the reds, oranges, and yellows of firelight and earth. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. #100709 at 26.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. Rather than a studied accent, #C02C0D takes 11.2% - a bold allocation that saturates the composition's atmosphere. At 80 units of value range, the palette has the tonal breadth to sustain complex spatial readings. In the context of Marsden Hartley's full range of palettes, group 5 represents one movement in an ongoing chromatic dialogue.
