Mid-key values give Domenichino its characteristic quietness - nothing blazes, nothing disappears. 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 highest-chroma note - #B78D2F - appears at just 3.9%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Domenichino's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
