Low-key values are the structural spine of El Greco, giving it gravity and atmosphere. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The dominant colour, #0B0908, takes 25.0% of the total area, establishing the overall mood before any other hue is introduced. At 7.8%, #5B4437 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. From deepest dark to palest light, the palette traverses 70 units of the value scale - a span that creates natural depth. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. This is palette 14 of El Greco's sequence - a single chapter in a chromatic story told across many works.
