Robert Spencer 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. Only 8.2% is devoted to #8491B5, yet that small allocation delivers the palette's entire chromatic tension. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Robert Spencer's palette 10 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
