「DEVIL'S NIGHT」は、10月31日のハロウィンを告知する縦型ポスターで、暗いゴシックホラー調です。とがった銀灰色の金属質ブラックレター文字に赤い血が滴り、黒地に2行で積み重ねられ、その下に「OCT 31」、さらに暗い草の上にうっすら黄緑の光があります。見出し、日付の行、背景の情景を、ご自身のイベント名や詳細に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. Dark vertical flyer format, 9:16. Near-black background with faint aged dark paper texture at 5% opacity. Single candle light from directly below, warm amber upward cast. 'DEVIL''S NIGHT' as main headline in upper third, filling 75% width. 'OCT 31' as secondary line below, centered, smaller scale. Deep shadow above and below. Halloween party flyer aesthetic. 9:16 vertical format.
