Charles Willson Peale is low-key throughout, a quality associated with Nocturnal Bister - deep shadows dominate the composition. Warmth dominates - the palette of Charles Willson Peale leans heavily on the yellow-orange-red arc of the colour wheel. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #141213 at 29.6% - sets the character of the whole composition. Only 2.6% is devoted to #BC6A3B, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Palette 10 sits within the larger chromatic argument that Charles Willson Peale's complete body of work advances.
