Romualdo Locatelli occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #B89A6C, is reserved to 8.3% of the surface, where it acts as a focal punctuation. The full value range is 69 units: broad enough to build convincing three-dimensional form. This is the light Romualdo Locatelli preferred, made measurable.
