The value structure of Biedermeier is mid-key: quiet, controlled, and cohesive. Built on cool foundations: the palette favours the blue-cyan-green arc. All colours lean toward grey, building depth through value rather than colour punch. The saturated accent, #D6D4B5, registers at 10.7% - sparse enough to feel like a deliberate surprise. 69 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
