The value structure of Simplício Rodrigues de Sá is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The saturated accent, #7E4551, registers at 1.8% - sparse enough to feel like a deliberate surprise. The value range of 46 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. Palette 3 sits within the larger chromatic argument that Simplício Rodrigues de Sá's complete body of work advances.
