Richard Jack works almost entirely in the lower half of the value scale, privileging depth over brilliance. Warm hues command this palette; Richard Jack favours the reds, oranges, and yellows of firelight and earth. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Richard Jack gives 32.2% of the composition to a single #1F1F23 - a decisive chromatic anchor. The saturated accent, #5E271A, registers at 6.6% - sparse enough to feel like a deliberate surprise. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. Richard Jack's palette 7 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
