Values in Jan van Os rest in the mid-range - neither dramatically lit nor steeped in shadow. Jan van Os 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. #A15126 delivers the chromatic peak at only 4.0% - a small shot of colour with outsized visual impact. The value range spans 81 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Jan van Os's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
