The value structure of Proto Renaissance is mid-key: quiet, controlled, and cohesive. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The highest-chroma note - #784539 - appears at just 5.4%, deployed as a precision accent against the quieter ground. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings.
