Gustav Marx distributes its values across the middle register, creating harmony without high contrast. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #342514 at 5.0% is both the most chromatic and one of the largest colours in the palette - chroma as mass rather than as highlight. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Gustav Marx's instinctive sense of how much of each quality the eye can hold.
