Emerald lacquer, black shale & terracotta.

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
Green that holds the whole room.
Emerald can take the walls when everything around it is warm and dark: terracotta floors, black stone, coffee-brown wood and a little gold leaf. Keep the cut-emerald green for one velvet sofa or a glass lamp so the room has a brightest point.

Sources & interpretation
An imagined colonial living room and specimen tray inspired by the Muzo district. Stone facts are from GIA; the room is not a record of a real place, and the colours were sampled from the generated specimen drawer. This study makes no claims about healing or other properties of the stone.
The palette follows the authored material references in this collection. Room, object and material imagery were created for this study. These are imagined settings, with no affiliation to the fictional interface brands.
The controls explore screen composition, not physical pigment recipes or material measurements. Image rights · Image permissions
