Ethel Léontine Gabain is high-key - luminous, open, and weighted toward light. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. The highest-chroma note - #4F5431 - appears at just 7.8%, deployed as a precision accent against the quieter ground. The value range spans 64 units across the palette, providing the full gamut from deep shadow to near-white and ensuring clear tonal hierarchy. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. This is palette 3 of Ethel Léontine Gabain's sequence - a single chapter in a chromatic story told across many works.
