Thomas Hudson is low-key throughout, a quality associated with Obsidian Sienna - deep shadows dominate the composition. Thomas Hudson builds on cool foundations: the palette favours the blue-cyan-green arc. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. A single dominant - #141411 at 28.5% - sets the character of the whole composition. The most saturated colour, #CBAF85, is reserved to 1.1% of the surface, where it acts as a focal punctuation. At 58 units of value range, the palette has the tonal breadth to sustain complex spatial readings. Together these qualities place Thomas Hudson firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. Palette 5 sits within the larger chromatic argument that Thomas Hudson's complete body of work advances.
