Jean Leon Gerome Ferris sits in the centre of the value range, lending the palette a sense of even, sustained light. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The saturated accent, #C57792, registers at 3.3% - sparse enough to feel like a deliberate surprise. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is the light Jean Leon Gerome Ferris preferred, made measurable.
