Values in Pietro Antonio Rotari rest in the mid-range - neither dramatically lit nor steeped in shadow. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #5A2F1C, is reserved to 0.0% of the surface, where it acts as a focal punctuation. A value spread of 57 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Taken together, these qualities constitute Pietro Antonio Rotari's chromatic voice - distinctive enough to be read across an entire body of work.
