Low-key values are the structural spine of Jan Lievens, giving it gravity and atmosphere. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. At 32.6%, #0F0E0E functions less as a colour accent and more as a complete atmospheric environment. #A58156 functions as the palette's exclamation mark: highest chroma, lowest percentage (4.7%). From deepest dark to palest light, the palette traverses 66 units of the value scale - a span that creates natural depth. This tonal restraint is characteristic of the Jan Lievens approach: colour serves light, not the reverse. This is palette 4 of Jan Lievens's sequence - a single chapter in a chromatic story told across many works.
