Charles Le Brun occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Yellow, ochre, sienna: warm hues that Charles Le Brun deploys 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 - #2A364F - appears at just 2.8%, deployed as a precision accent against the quieter ground. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Charles Le Brun's sequence - a single chapter in a chromatic story told across many works.
