Peter Paul Rubens occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm hues command this palette; Peter Paul Rubens favours the reds, oranges, and yellows of firelight and earth.

Spanning 52 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation.
