Simplício Rodrigues de Sá keeps values measured and balanced, a hallmark of tonal restraint. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. At 8.4%, #97571F carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The palette spans 51 value units: a measured range that delivers coherence over drama. Palette 4 sits within the larger chromatic argument that Simplício Rodrigues de Sá's complete body of work advances.
