Paolo Porpora dwells firmly in the shadows, with no more than a whisper of light. Temperature is cool-dominant, with blue and green families claiming the largest areas. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #514C2E, is reserved to 5.7% of the surface, where it acts as a focal punctuation. Value range is moderate at 44 units - enough contrast for legibility, not so much as to fragment the tonal unity. Together these qualities place Paolo Porpora firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 4 sits within the larger chromatic argument that Paolo Porpora's complete body of work advances.
