Expressionism occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. #D07E49 delivers the chromatic peak at only 13.3% - a small shot of colour with outsized visual impact. The palette spans 49 value units: a measured range that delivers coherence over drama.
