「HT」は FontVibe AI で作成した炎と煙の文字エフェクトです。燃え盛る炎と煙のエフェクト、劇的な熱波と燃え残りの輝きを表現します。

Real combustion physics: white-yellow inner core transitioning through orange and deep red to wispy blue-grey outer tips. Turbulent flame tongues surge upward with natural random motion. Dense dark smoke billows in heavy rolling columns, curling upward — charcoal and near-black with faint translucency at edges. Firelight self-illuminates from below with warm amber-orange cast. Dramatic upward rim from intense heat source underneath. Background: deep charcoal haze with faint ember glow — not pure black. Cinematic fire photography quality. 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 flame-and-smoke material, the combustion glow and the cast light. FALLBACK MATERIAL: if the font carries no material of its own, render the letters ablaze — a white-yellow core through orange to deep red flame tongues with dark rolling smoke and warm self-illumination from below. COLOR PRIORITY: keep the font's own colors if specified; otherwise the natural fire spectrum of amber, orange and deep red. Two monumental letterforms reading "HT" emerge from a field of active combustion, their surfaces consumed by physically realistic flame: dense white-yellow incandescent cores at the hottest lower edges, transitioning through saturated amber and orange into deep red flame sheets, with torn blue-grey wisps at the cooling tips. Turbulent flame tongues rise in irregular, wind-driven curls from every exposed edge, while fine ember sparks lift through the air in varied sizes and depths. Heavy charcoal smoke forms rolling columns around the letters, nearly black at the densest folds and translucent at the illuminated fringes. Intense orange firelight radiates upward from beneath, casting a sharp heated rim across the forms and lighting suspended soot. Visible heat-distortion ripples warp the haze immediately above the burning text. Background is deep charcoal haze rather than flat black, with a faint low volcanic glow, drifting ash, and sparse distant embers. High-contrast cinematic fire photography, ray-traced volumetric smoke, crisp flame detail, blackened negative space surrounding the compact monogram.
