Tonalism distributes its values across the middle register, creating harmony without high contrast. Warm and cool are kept in productive tension, creating the kind of chromatic harmony that sustains the eye. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #695030 - appears at just 13.8%, deployed as a precision accent against the quieter ground. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth.
