The value structure of Heywood Hardy is mid-key: quiet, controlled, and cohesive. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #F6EEE0 delivers the chromatic peak at only 3.7% - a small shot of colour with outsized visual impact. At 72 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette reads as an Impressionist one - light-biased, chromatically direct, and built on temperature contrast rather than value opposition. Heywood Hardy's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
