American Realism occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Built on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The highest-chroma note - #D3A465 - appears at just 3.5%, deployed as a precision accent against the quieter ground. The palette spans 49 value units: a measured range that delivers coherence over drama. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
