Walter Osborne 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 saturated accent, #958961, registers at 9.1% - sparse enough to feel like a deliberate surprise. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. Walter Osborne's palette 1 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
