Rose O'Neill occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 3.2%, #C56D37 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. The full value range is 67 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Rose O'Neill's palette 3 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
