Jacob Ochtervelt is built on dark foundations, with values clustered toward shadow. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. Jacob Ochtervelt gives 30.0% of the composition to a single #231D19 - a decisive chromatic anchor. #503C2A delivers the chromatic peak at only 6.5% - a small shot of colour with outsized visual impact. 49 units of value spread create a palette that is varied but unified - contrast in the service of harmony. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 7 of Jacob Ochtervelt's sequence - a single chapter in a chromatic story told across many works.
