Mid-key values give Karl Wilhelm Diefenbach its characteristic quietness - nothing blazes, nothing disappears. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. A single dominant - #333224 at 28.6% - sets the character of the whole composition. The most saturated colour, #D3DEC8, is reserved to 4.0% of the surface, where it acts as a focal punctuation. A value spread of 66 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that Karl Wilhelm Diefenbach's complete body of work advances.
