Petrus Christus occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature reads distinctly warm: the reds and earth tones from Petrus Christus carry the compositional weight. Mid-saturation across the board: the palette has colour character without chromatic excess. #AE4536 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.7%). A value spread of 61 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 2 sits within the larger chromatic argument that Petrus Christus's complete body of work advances.
