Giuseppe Tominz is low-key throughout, a quality associated with Obsidian Sienna - deep shadows dominate the composition. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. All colours lean toward grey, building depth through value rather than colour punch. 43.1% of the palette belongs to #151615, a concentration that makes it the unmistakable visual centre. The highest-chroma note - #D4BB85 - appears at just 1.4%, deployed as a precision accent against the quieter ground. The value range spans 60 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. This tonal restraint is characteristic of the Giuseppe Tominz approach: colour serves light, not the reverse. In the context of Giuseppe Tominz's full range of palettes, group 7 represents one movement in an ongoing chromatic dialogue.
