Thomas Alexander Ferguson Graham 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. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #5D3618, is reserved to 5.3% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 61 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. Palette 1 sits within the larger chromatic argument that Thomas Alexander Ferguson Graham's complete body of work advances.
