「Ember」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. Pure black void background — deep charcoal haze bleeding inward from the edges with faint amber-orange ember glow at the lower periphery, scattered incandescent spark particles drifting upward like burning snow against the dark. 'Ember' rendered in fire-engulfed letterforms occupying a generous portion of the frame, letters crowned with surging flame tongues — white-yellow inner combustion core transitioning through vivid orange into deep crimson-red at the outer edges, each letterform wrapped in a living aura of turbulent fire. Dense dark smoke billows upward from the letter crowns, rolling in heavy charcoal columns with faint translucency at the wispy curling tips. Intense heat shimmer distortion ripples visibly above every letter — the air above warping in glassy thermal waves from the concentrated heat source below. Warm amber-orange self-illumination radiates outward from the burning letterforms, casting a dramatic upward rim light that carves each letter out of the surrounding darkness with high-contrast chiaroscuro depth. Ember sparks and micro-particles rain upward in chaotic arcs throughout the full frame height. Cinematic fire photography quality, octane render, 8k sharp detail, real combustion physics.
