Pierre-Narcisse Guerin distributes its values across the middle register, creating harmony without high contrast. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. Only 7.1% is devoted to #D1C5A4, yet that small allocation delivers the palette's entire chromatic tension. 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. Pierre-Narcisse Guerin's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
