Jean-Baptiste Carpeaux is low-key throughout, a quality associated with Smoldering Cinder - deep shadows dominate the composition. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 30.2%, #151216 functions less as a colour accent and more as a complete atmospheric environment. The highest-chroma note - #53221D - appears at just 2.1%, deployed as a precision accent against the quieter ground. At 64 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Palette 3 sits within the larger chromatic argument that Jean-Baptiste Carpeaux's complete body of work advances.
