The value structure of Walter Gramatté is mid-key: quiet, controlled, and cohesive. Temperature is cool-dominant, with blue and green families claiming the largest areas. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #86724A - appears at just 8.6%, deployed as a precision accent against the quieter ground. 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 Gramatté's palette 4 carries its own internal logic while remaining in conversation with the artist's broader colour intelligence.
