Darkness anchors William Merritt Chase; light is rationed, creating dramatic contrast rather than open air. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #161314 at 48.4% - sets the character of the whole composition. #694B31 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.2%). At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities place William Merritt Chase firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 20 sits within the larger chromatic argument that William Merritt Chase's complete body of work advances.
