pastorale keeps values measured and balanced, a hallmark of tonal restraint. 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. The highest-chroma note - #9B6046 - appears at just 3.5%, deployed as a precision accent against the quieter ground. At 47 units across the value scale, the palette keeps contrast readable without letting it dominate.
