Luca Giordano distributes its values across the middle register, creating harmony without high contrast. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #C6994F functions as the palette's exclamation mark: highest chroma, lowest percentage (5.8%). At 62 units of value range, the palette has the tonal breadth to sustain complex spatial readings. This is palette 4 of Luca Giordano's sequence - a single chapter in a chromatic story told across many works.
