Lina Bo Bardi built her architecture out of two materials held in frank tension: raw board-formed concrete and bold cherry-red structure. At MASP São Paulo glass picture-easels hang inside a red beam frame; at SESC Pompéia a converted factory carries red circulation and sliding partitions across stripped concrete masses.

This system distills that harmony — a mid-tone concrete-gray ground, frank saturated red on structural members, heavy industrial grotesque type, and surfaces left rough, matte, and honestly constructed with their form marks showing.
