The value structure of Giovanni Battista Moroni is mid-key: quiet, controlled, and cohesive. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. 29.2% of the palette belongs to #0B080E, a concentration that makes it the unmistakable visual centre. Only 3.6% is devoted to #A17142, yet that small allocation delivers the palette's entire chromatic tension. 76 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 1 of Giovanni Battista Moroni's sequence - a single chapter in a chromatic story told across many works.
