American Realism is strongly light-biased - shadow is suggested rather than declared. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #D0D9E5 at 32.4% - sets the character of the whole composition. The saturated accent, #67331F, registers at 0.7% - sparse enough to feel like a deliberate surprise. The full value range is 64 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky.
