Thomas Gainsborough occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Temperature is cool-dominant, with blue and green families claiming the largest areas. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. The saturated accent, #BE9D3A, registers at 9.4% - sparse enough to feel like a deliberate surprise. 56 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Thomas Gainsborough's palette 8 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
