Francesco Francia sits in the centre of the value range, lending the palette a sense of even, sustained light. Cool tones set the register here - the blues and greens easily outweigh any warm accents. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #2B596A delivers the chromatic peak at only 5.6% - a small shot of colour with outsized visual impact. 56 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 Francesco Francia's sequence - a single chapter in a chromatic story told across many works.
