「Buen dia」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. Cinematic fire typography for the exact rendered text “Buen dia”. The letterforms are consumed by real combustion: dense white-yellow incandescent cores at the hottest edges, transitioning into saturated amber-orange and deep red flame sheets, with thin turbulent flame tongues lifting naturally from contours. Dark charcoal smoke rolls from the burning surfaces in layered columns, near-black at the dense cores and translucent blue-grey at torn outer edges. Fine ember sparks drift upward through the frame, varying from pinprick gold to dim red ash. Strong heat distortion ripples warp the surrounding air directly above the burning text. A deep charcoal-black haze background holds faint distant ember glow rather than flat black, preserving separation around every flame tip. Intense firelight rises from beneath, producing a warm amber cast, hard upward rim illumination, and subtle red reflections in the smoke. Keep the words exactly as written, with “Buen dia” as the sole visual message and clear, fully legible letter shapes beneath the flame treatment. High-contrast cinematic fire photography, physically based combustion detail, volumetric smoke, ray-traced glow, crisp ember particles, controlled negative space around the burning title.
