「NIGHTFALL」は、暗い中世ホラー調のゴシック風タイトルカードです。とがったブラックレターの大文字は風化した石の質感で、淡いグレーから温かい琥珀色へ変化し、一行で配置され、下には火のともるろうそくと緑の霧、背景は薄暗い石壁です。タイトル文字や、必要ならろうそくと霧の色を、自分の物語やゲーム、イベントに合わせて差し替えて作り直せます。

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. Rough ancient limestone wall texture fills the background, aged grey stone, deep chisel marks between blocks. Single beeswax candle at floor level directly below, warm amber upward-cast flame as the only light source. Deep shadow fills the upper two-thirds of the frame. 'NIGHTFALL' centered, filling 76% of square width. Cold, ancient, medieval Halloween atmosphere. 1:1 square.
