Jacques Réattu sits in the centre of the value range, lending the palette a sense of even, sustained light. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The highest-chroma note - #471209 - appears at just 5.4%, deployed as a precision accent against the quieter ground. At 46 units across the value scale, the palette keeps contrast readable without letting it dominate. This is palette 4 of Jacques Réattu's sequence - a single chapter in a chromatic story told across many works.
