Last dance at the empty ballroom | art-deco masquerade banner background

An elegant halloween event background: a wide art-deco ballroom banner in oxblood, midnight plum and bone with engraved aged-brass bands, mirrored flanking panels and candle sconces, and one pair of gilded masquerade masks leaning cheek to cheek on a banquet table at the lower left; the central plum field stays clear for event text.

Prompt

Paint the entire image in flat decorative art-deco geometry, a poster-like stylization built from broad stepped and fan-shaped planes in deep oxblood red, midnight plum and warm bone, every edge trimmed with aged-brass bands whose fine parallel grooves carry a restrained simulated foil sheen; surfaces stay matte and mineral, and only the brass glints, with crisp slivers of light along groove edges on a dark plum ground. The scene is an empty ballroom on a wide 16:9 banner frame, seen head-on down a strict axis of symmetry. Two tall flanking wall panels mirror each other at the left and right thirds, each engraved with stepped fan and chevron motifs and carrying one small candle sconce; between them the entire central band is one uninterrupted dark plum field kept completely clear and unlettered, reserved as empty copy space. One long banquet table spans the lower edge, its oxblood cloth and brass-trimmed drape running past both bottom corners as room furnishing; on the table's far edge, left of centre, a single pair of gilded masquerade masks — one fox-faced, one round-eyed domino — lean together cheek to cheek with empty eye holes, fully inside the frame with clear space on every side. Warm candle-orange glints run along every groove and table trim from the two sconces while the plum ground stays cool; each mask's foil surface carries one restrained highlight. No other props crowd the field; the emptiness is the design.
