Values in Peter Paul Rubens rest in the mid-range - neither dramatically lit nor steeped in shadow. Peter Paul Rubens builds on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. Only 6.1% is devoted to #602F21, yet that small allocation delivers the palette's entire chromatic tension. The full value range is 56 units: broad enough to build convincing three-dimensional form. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 6 of Peter Paul Rubens's sequence - a single chapter in a chromatic story told across many works.
