Concrete Dark sets the weight of the palette in authority and restraint, and Panel Red is the swatch that breaks rank: a single red that stops the set reading as one note. Panel Red and Panel Blue sit on opposite sides of the temperature line, which is the tension the palette runs on and the pair to hold apart. Concrete Dark and Raw Concrete sit 57 points of lightness apart, enough to separate a foreground from a background without forcing it.
Concrete Dark is black's softer relative, still authoritative, but with enough warmth to feel considered rather than severe.
Panel Red reads as pure adrenaline: alarm, desire, the color of things that move fast.
Panel Blue is the most trusted color in color psychology: competence, stability, calm, used constantly by institutions that need to be believed.
Panel Yellow an electric, high-visibility yellow: caution and euphoria share the same wavelength here.
Raw Concrete a burnt or terracotta orange, warmth read through a rustic, sun-worn filter.
The twentieth century's great rupture - Gropius, Le Corbusier, and Mies van der Rohe dismantled centuries of ornament to build the world from first principles: structure, light, function, and the flat roof as manifesto.
