Frank Holl keeps values measured and balanced, a hallmark of tonal restraint. Yellow, ochre, sienna: warm hues that Frank Holl deploys as the palette's primary energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #D1B26C functions as the palette's exclamation mark: highest chroma, lowest percentage (4.5%). The value range spans 61 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This is the light Frank Holl preferred, made measurable.
