Low-key values are the structural spine of Peter Angellis, giving it gravity and atmosphere. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #A0532B, is reserved to 3.5% of the surface, where it acts as a focal punctuation. 49 units of value spread create a palette that is varied but unified - contrast in the service of harmony. Together these qualities place Peter Angellis firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. This is palette 4 of Peter Angellis's sequence - a single chapter in a chromatic story told across many works.
