The palette of Thomas Gainsborough sits in the lower register of the value scale - dense, contained, and weighted. Thomas Gainsborough orchestrates warmth above all else - reds, ambers, and siennas take the lead. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. At 34.8%, #191112 functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #E4CB9A, is reserved to 1.7% of the surface, where it acts as a focal punctuation. The value range spans 66 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The combination of low values, muted chroma, and compressed range is the signature of the Tonalist mode - painting as atmosphere. In the context of Thomas Gainsborough's full range of palettes, group 13 represents one movement in an ongoing chromatic dialogue.
