Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #A69070 functions as the palette's exclamation mark: highest chroma, lowest percentage (8.8%). 68 units of value range underpin the palette's structural clarity: the eye always knows where light falls.
