The value structure of Franz Marc is mid-key: quiet, controlled, and cohesive. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. All colours lean toward grey, building depth through value rather than colour punch. The highest-chroma note - #A23621 - appears at just 6.4%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 72 units of the value scale - a span that creates natural depth. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Palette 4 sits within the larger chromatic argument that Franz Marc's complete body of work advances.
