Mid-key values give Impressionism its characteristic quietness - nothing blazes, nothing disappears. The palette tilts toward cool - blues and silver-greys carry the structural weight. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #5F6744 functions as the palette's exclamation mark: highest chroma, lowest percentage (6.7%). The full value range is 60 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
