vtxterrelagune, A winter city at blue hour viewed from above a quiet street corner, with stepped red-clay and ivory facades, a dark teal sky and a few warm ochre window rectangles. Snow traces the rooftops and pavement; the street opens into a small square at the center, where one distant adult walks beneath a dark umbrella. The entire image, including buildings, person, snow, windows and sky, is made of fine colored sand grains. Tiny pale grains articulate window frames and roof edges, and mixed teal-ivory grains create cold shadow planes. Use only the Terre et lagune palette. The scene's depth remains a color-based illusion across the matte sand layer, with slight localized thickness at a few short snow-covered roof contacts.
