Thomas Francis Dicksee is low-key throughout, a quality associated with Obsidian Sienna - deep shadows dominate the composition. Yellow, ochre, sienna: warm hues that Thomas Francis Dicksee deploys as the palette's primary energy. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 35.8%, #0F0B09 functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #524C34, is reserved to 5.8% of the surface, where it acts as a focal punctuation. The value range spans 58 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. Together these qualities place Thomas Francis Dicksee firmly in the tonal tradition - concerned with mood and atmosphere rather than chromatic display. This is palette 5 of Thomas Francis Dicksee's sequence - a single chapter in a chromatic story told across many works.
