Values in Alfred Roll rest in the mid-range - neither dramatically lit nor steeped in shadow. Alfred Roll orchestrates warmth above all else - reds, ambers, and siennas take the lead. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #C4733C, is reserved to 3.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 78 units of the value scale - a span that creates natural depth. Taken together, these qualities constitute Alfred Roll's chromatic voice - distinctive enough to be read across an entire body of work.
