Neoclassicism is high-key - luminous, open, and weighted toward light. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #234561 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.5%). A value spread of 72 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
