Charles Olivier de Penne occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is measured and controlled, giving the palette presence without visual aggression. #AB382A delivers the chromatic peak at only 2.4% - a small shot of colour with outsized visual impact. At 60 units of value range, the palette has the tonal breadth to sustain complex spatial readings. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Charles Olivier de Penne's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
