The value structure of Tonalism is mid-key: quiet, controlled, and cohesive. The palette orchestrates warmth above all else - reds, ambers, and siennas take the lead. Mid-range chroma keeps the palette grounded - colourful but not strident. #8F481C at 31.6% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. #DAA469 is not a small accent - at 4.7% it qualifies as a major presence and gives the palette its chromatic identity. Value range is moderate at 54 units - enough contrast for legibility, not so much as to fragment the tonal unity.
