tronie sits in the centre of the value range, lending the palette a sense of even, sustained light. Yellow, ochre, sienna: warm hues deployed as the palette's primary energy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #76270B delivers the chromatic peak at only 2.8% - a small shot of colour with outsized visual impact. The full value range is 56 units: broad enough to build convincing three-dimensional form.
