「Happy Halloween」は FontVibe AI で作成した血のしたたるフォントの文字エフェクトです。濡れた暗赤色の表面を持つ太い深紅の文字。長い血の滴は丸い粒で終わり、横からの光を受けて真っ黒な背景に浮かびます。

Thick crimson blood saturating every surface — viscous, high-density fluid with authentic physical behavior: large tear-shaped drops suspended at each drip terminus with surface tension visible at the meniscus, connecting streams thinning as they extend downward, deep near-black pooling where blood accumulates. Material properties: subsurface scattering gives deep red glow when backlit, specular gloss on convex drip surfaces catching directional light, matte-dark at clotted pooling zones. Blood color gradient from bright arterial red (#CC0000) at active drip streams to near-black clot (#3D0000) at base pools. Gravity-driven physics — every drip pulled downward with anatomically accurate tension. Horror film practical effects quality — not painted, not stylized, photorealistic blood. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the viscous blood fluid physics, the suspended drips and the pooling. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as viscous crimson blood letters with tear-shaped drops held by surface tension, thinning connecting streams and near-black pooling. COLOR PRIORITY: keep the font's own colors if specified; otherwise arterial red (#CC0000) grading to near-black clot (#3D0000). Wide 16:9 Halloween greeting composition. Render the exact words “Happy Halloween” as the dominant centerpiece, arranged on two balanced lines with generous breathing room around the lettering. The letters are saturated deep crimson, glossy and wet, with thick viscous blood coating every surface. Heavy gravity-pulled drips hang from the lower edges, broad at their source and narrowing into rounded teardrop terminals; a few drops hover just below the letters, held by visible surface tension. Fresh streams glow arterial red where cold side light passes through them, fading into near-black maroon in the shadows and pooled clots. Set everything against a pure black background with no warm colors or decorative clutter. A restrained, cold red rim light from one side picks out slick convex surfaces while the opposite sides sink into deep shadow. Add subtle dark pooling beneath the words and a sparse scattering of tiny blood droplets near the longest drips. Keep the phrase highly legible and festive in layout, but give the material an authentically heavy, visceral horror-film quality: photorealistic wet sheen, dark clotted edges, and no watery thin streaks.
