High Renaissance sits in the centre of the value range, lending the palette a sense of even, sustained light. The palette balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. The most saturated colour, #7A4425, is reserved to 5.1% of the surface, where it acts as a focal punctuation. The full value range is 57 units: broad enough to build convincing three-dimensional form.
