Ethel Léontine Gabain 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. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The highest-chroma note - #A59469 - appears at just 8.1%, deployed as a precision accent against the quieter ground. The value range of 54 units sits in the comfortable middle: enough depth, enough light, neither extreme. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is the light Ethel Léontine Gabain preferred, made measurable.
