Mid-key values give Robert Henri its characteristic quietness - nothing blazes, nothing disappears. Robert Henri 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. The highest-chroma note - #BB7646 - appears at just 1.7%, deployed as a precision accent against the quieter ground. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 6 of Robert Henri's sequence - a single chapter in a chromatic story told across many works.
