A material study / 054
Rome: Porphyry & Serpentine
Burgundy and emerald, cut from Roman stone.
Burgundy and emerald taken from the stones of Rome’s Cosmati floors: imperial red porphyry, green porphyry, giallo antico and white marble, brought into a library, a kitchen and a Christmas room.
01 / The palette
Six colors, one atmosphere.
Screen colors are authored interpretations. Material photographs show surface character; they are not calibrated color samples.
02 / Play with the composition
Burgundy and emerald, set in stone.
Burgundy and emerald work when one stays a surface and the other a stone. Let white marble carry the largest area, give emerald the walls, joinery or upholstery, and keep porphyry red to slabs and roundels: a table top, an island, a floor inlay. Giallo antico and gilt are the small warm notes.

Sources & interpretation
An imagined Roman apartment and stone flat lay inspired by Cosmati floors. The stones are real and named, but the rooms are not records of a real home, and the colours were sampled from the generated flat lay rather than from a church pavement. Imperial porphyry is no longer quarried; almost all of it seen today was cut in Roman times.
