"HAPPY HALLOWEEN" ist ein Grußhintergrund mit hängendem Schild im illustrierten Stil einer mondhellen Halloween-Nacht. Ein Vollmond mit Fledermäusen steht über einem Spukhaus, einem Friedhof und kahlen Bäumen in Indigo, dazu leuchten orangefarbene Kürbislaternen auf einer Holzveranda; das Schild hängt am rechten Pfosten in schwarzen Großbuchstaben. Ersetze den Schildtext durch deinen eigenen Gruß, Namen oder Partydaten, um deine eigene Version zu gestalten.

Create a finished 16:9 video-call background for an office Halloween party, in a clean flat illustration with fine paper grain and a trace of soft mist between distant gravestones. Show a moonlit outdoor porch at night, framed by dark porch posts and a few steps. Preserve a broad, calm, uncluttered opening across the center-left for the caller: no text, moon, bats, furniture, pumpkins or strong focal details in that space. Put the visual detail around the edges and toward the right. In the upper-right sky, show a huge full moon with a cool pale rim light; include a few small bats crossing near it. In the distance, silhouette a haunted house with warm glowing windows, a crooked graveyard fence, gravestones and bare twisted trees. Along the lower edge, arrange a row of glowing jack-o-lanterns, with their warm orange light contained to the pumpkins and the house windows; keep the cool moonlit indigo-purple night as the base. Add one small, clearly readable wooden Halloween sign on the far-right porch post. Its only wording is exactly “Happy Halloween”. Set the words in bold, heavy, upright display sans-serif capitals with wide solid strokes, open counters and small bat-wing flares on flat stroke ends; keep every letter unmistakably readable at video-call size. Give the sign a restrained moon-white painted face and cool moonlit edges, with no extra lettering. Do not put any other text in the image. Keep the caller area visually quiet and lower-contrast than the edge details, with a few faint porch-board lines only; no vignette or central object. Warm pumpkin orange is reserved for the jack-o-lanterns and house windows. The overall read is a welcoming, spooky Halloween porch, designed to sit behind a person on a video call.
