William Banks Fortescue occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. The most saturated colour, #A38D6D, is reserved to 10.0% of the surface, where it acts as a focal punctuation. A value spread of 69 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light William Banks Fortescue preferred, made measurable.
