Adam de Colone is low-key throughout, a quality associated with Tenebrous Sienna - deep shadows dominate the composition. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Adam de Colone gives 35.5% of the composition to a single #0D0E0D - a decisive chromatic anchor. The saturated accent, #C0943A, registers at 1.2% - sparse enough to feel like a deliberate surprise. The full value range is 70 units: broad enough to build convincing three-dimensional form. This tonal restraint is characteristic of the Adam de Colone approach: colour serves light, not the reverse. This is palette 2 of Adam de Colone's sequence - a single chapter in a chromatic story told across many works.
