Jacob Ochtervelt keeps values measured and balanced, a hallmark of tonal restraint. Jacob Ochtervelt balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #412B21 functions as the palette's exclamation mark: highest chroma, lowest percentage (10.2%). At 67 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 4 sits within the larger chromatic argument that Jacob Ochtervelt's complete body of work advances.
