Low-key values are the structural spine of Jean-Baptiste Monnoyer, giving it gravity and atmosphere. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #B97C70 - appears at just 1.9%, deployed as a precision accent against the quieter ground. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This tonal restraint is characteristic of the Jean-Baptiste Monnoyer approach: colour serves light, not the reverse. This is palette 4 of Jean-Baptiste Monnoyer's sequence - a single chapter in a chromatic story told across many works.
