Light floods Naturalism; the palette keeps values pale and airy across its range. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. A single dominant - #EADEC3 at 43.7% - sets the character of the whole composition. #5A5B2A functions as the palette's exclamation mark: highest chroma, lowest percentage (6.8%). The full value range is 71 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
