Theodor Leopold Weller keeps values measured and balanced, a hallmark of tonal restraint. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 4.8%, #7B4424 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 79 units of value range, the palette has the tonal breadth to sustain complex spatial readings. 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 Theodor Leopold Weller's complete body of work advances.
