「NIGHTFALL」は FontVibe AI で作成したホラーの文字エフェクトです。血が滴る細くぎざぎざした赤い文字。水没したトンネルのただ一つの裸電球に照らされ、暗く静かな水面に映ります。

Consumer Halloween horror typography. Graphic, bold, and immediately readable as "spooky" -- the visual language of seasonal design: T-shirts, party invites, phone cases, social media posts. HALLOWEEN HORROR RULES (apply to every shot): - Underlighting by default. Warm amber-orange key from directly below, deep shadow filling the upper two-thirds. Candle-beneath-the-face. - Extreme contrast, no mid-tones. Lit surfaces near-maximum brightness, shadow zones near-black. Nothing gradual, nothing soft. - Background always dark. Near-black with warm amber or sickly yellow-green secondary fill at very low opacity. No neutral grays. - Color regime: blood is deep candy-red to dark crimson; fire is amber-orange with bright core; decay is dark brown, rust, mold green. - Graphic and immediate. If the effect reads clearly on a printed T-shirt or party poster, it is correct. FORBIDDEN: cinematic framing rules, single-light psychological analysis, desaturated fog atmospherics, flat studio lighting. When no specific material is defined by the font: default lighting environment -- warm amber-orange underlighting from directly below, deep shadow above, near-black background with sickly yellow-green secondary fill at 8% opacity at ground level. Close-up of aged stone archway, 1:1 square. Rough-hewn limestone arch frame with deep shadow interior beyond. Single torch light from below-left at 25% intensity, warm amber, casting right-ward shadow across stone surface. Cold moonlight ambient from upper right. 'NIGHTFALL' centered within the arch opening, filling 72% of square.
