Carl Schleicher keeps values measured and balanced, a hallmark of tonal restraint. Cool tones set the register here - the blues and greens easily outweigh any warm accents. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. #422E1C delivers the chromatic peak at only 8.9% - a small shot of colour with outsized visual impact. From deepest dark to palest light, the palette traverses 58 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. These proportions encode Carl Schleicher's instinctive sense of how much of each quality the eye can hold.
