Peter Jacob Horemans keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. Peter Jacob Horemans gives 25.0% of the composition to a single #342E1E - a decisive chromatic anchor. The most saturated colour, #68331C, is reserved to 3.2% of the surface, where it acts as a focal punctuation. At 51 units across the value scale, the palette keeps contrast readable without letting it dominate. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 4 sits within the larger chromatic argument that Peter Jacob Horemans's complete body of work advances.
