The high-key values of Robert Russ give it an effulgent, almost bleached quality. Robert Russ tilts toward cool - blues and silver-greys carry the structural weight. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #211810 - appears at just 3.3%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 66 units of the value scale - a span that creates natural depth. 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 1 of Robert Russ's sequence - a single chapter in a chromatic story told across many works.
