John Henry Twachtman is high in key: pale, luminous, and filled with optical air. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is held at a comfortable level - distinct colours, but no single hue is allowed to overwhelm. #D8DAA0 at 8.3% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 49 units across the value scale, the palette keeps contrast readable without letting it dominate. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 2 sits within the larger chromatic argument that John Henry Twachtman's complete body of work advances.
