「KIDAFRO BIRTHDAY CELEBRATION 」は FontVibe AI で作成したバースデーの文字エフェクトです。白フチのくっきりした虹色ストライプの丸い大文字。紙吹雪と風船の束に囲まれ、ピンクからターコイズへの鮮やかなパーティー背景。

Joyful celebration light field — backgrounds drawn from deep midnight navy, velvety near-black, rich warm charcoal, and dark burgundy with subtle tonal warmth; every background holds visual weight and depth, never flat or pure white. Key light arrives from directly overhead at 85–90 degrees as a broad soft high-intensity wash — the quality of a grand celebration spotlight — landing evenly across the composition with minimal directional shadow. Secondary fill from both flanks simultaneously at 40–45 degrees at 50% key intensity eliminates shadow zones while preserving full three-dimensional volume. Atmospheric particles inhabit the mid-ground at low-medium density: fine confetti paper fragments, drifting sparkle glints, floating botanical petal shapes — their scale and density shift with direction energy. Color temperature shifts by context: cool electric spectrum (magenta, cyan, lime-green) deepens the darkness for neon party directions; warm rose-amber spectrum softens the background for floral calligraphy directions; full-saturation rainbow vivid for balloon party directions. Background depth is reinforced by a subtle corner vignette; the central field brightens toward maximum luminosity at the text zone. Letter surface material and texture are defined entirely by each font's own prompt_core — this style provides only the celebration light field and atmospheric environment. When no specific direction or font material is active: deep midnight navy background, overhead broad soft white key light at 90 degrees, fine multicolor confetti scatter at 10% scene density, equal-intensity soft fills from both flanks, no floor surface, no props. Create a finished, high-energy birthday celebration graphic featuring the exact words “KIDAFRO” and “BIRTHDAY CELEBRATION.” Set KIDAFRO as the dominant line, large and centered across the upper-middle, with BIRTHDAY CELEBRATION directly beneath it in a smaller but bold, clearly readable line. Preserve the client’s wording and spelling exactly. Use a vivid candy-colored party gradient, blending electric turquoise, hot pink, and rich violet, with a brighter central glow behind the words and deeper saturated color toward the corners. Surround the lettering with a dense, lively burst of multicolor confetti, tiny sparkling glints, and colorful balloons gathered along both sides and the outer edges; keep the center open so every word remains unmistakable. Add a few bright light streaks and warm celebratory bokeh to give the scene motion and depth. Give the words strong contrast against the background with crisp pale edging or a soft, clean shadow, while keeping the lettering’s own material and finish natural to its chosen style. The overall image should feel bold, joyful, vivid, and polished, like a striking modern birthday card, with energetic framing and a clear, uncluttered text hierarchy.
