The high-key values of Antonio Jacobsen give it an effulgent, almost bleached quality. 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. The highest-chroma note - #9BC6E3 - appears at just 8.4%, deployed as a precision accent against the quieter ground. The value range spans 72 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. This is palette 3 of Antonio Jacobsen's sequence - a single chapter in a chromatic story told across many works.
