Mid-key values give Expressionism its characteristic quietness - nothing blazes, nothing disappears. 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. The saturated accent, #C5A263, registers at 4.8% - sparse enough to feel like a deliberate surprise. At 53 units across the value scale, the palette keeps contrast readable without letting it dominate. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
