Darkness anchors Jean-François de Troy; light is rationed, creating dramatic contrast rather than open air. Jean-François de Troy keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The dominant colour, #13110D, takes 26.2% of the total area, establishing the overall mood before any other hue is introduced. #8E3B1C functions as the palette's exclamation mark: highest chroma, lowest percentage (5.7%). 58 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Jean-François de Troy's full range of palettes, group 8 represents one movement in an ongoing chromatic dialogue.
