Andrea del Castagno keeps values measured and balanced, a hallmark of tonal restraint. Andrea del Castagno balances warm and cool with remarkable evenness, giving the composition its characteristic vibrancy. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #917556, is reserved to 10.7% of the surface, where it acts as a focal punctuation. The full value range is 59 units: broad enough to build convincing three-dimensional form. Palette 2 sits within the larger chromatic argument that Andrea del Castagno's complete body of work advances.
