Theodore Rousseau occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Theodore Rousseau tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #917843 delivers the chromatic peak at only 6.4% - a small shot of colour with outsized visual impact. The full value range is 67 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of Theodore Rousseau's sequence - a single chapter in a chromatic story told across many works.
