Jan Hackaert distributes its values across the middle register, creating harmony without high contrast. A distinctly cool atmosphere runs through this palette: sky, water, and mist given colour form. All colours lean toward grey, building depth through value rather than colour punch. #A69157 functions as the palette's exclamation mark: highest chroma, lowest percentage (3.4%). Spanning 44 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Jan Hackaert's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
