Values in Petrus Christus rest in the mid-range - neither dramatically lit nor steeped in shadow. Petrus Christus orchestrates warmth above all else - reds, ambers, and siennas take the lead. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 6.9%, #E1CD96 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The palette is recognisably Petrus Christus's own: particular in its temperature, chroma, and the economy of its brightest note.
