The value structure of George Washington Lambert is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #745D29 - appears at just 7.6%, deployed as a precision accent against the quieter ground. 52 units of value spread create a palette that is varied but unified - contrast in the service of harmony. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 3 of George Washington Lambert's sequence - a single chapter in a chromatic story told across many works.
