Mid-key values give Peter Paul Rubens its characteristic quietness - nothing blazes, nothing disappears. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Colours are neither washed out nor blazing; they occupy the productive middle ground of the chroma scale. 31.4% of the palette belongs to #101116, a concentration that makes it the unmistakable visual centre. Only 6.6% is devoted to #B4461A, yet that small allocation delivers the palette's entire chromatic tension. At 63 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Palette 13 sits within the larger chromatic argument that Peter Paul Rubens's complete body of work advances.
