“Happy Birthday” is a Cyberpunk Electric Neon text effect text effect created with FontVibe AI. Classic neon tube glow effect — single vivid color, soft light bloom and the authentic warmth of a real neon sign.

rendered as real neon tube sign lettering. Letters formed from glowing neon tubes with authentic tube thickness variation, warm light bloom radiating outward with soft falloff, realistic neon color saturation — choose from electric blue, hot pink, acid green or golden yellow. Subtle tube reflection on a dark backing panel. 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 glass neon-tube material, the warm light bloom and the dark backing panel. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as glowing neon-tube letters with authentic tube thickness, soft outward bloom and subtle reflection on a dark backing panel. COLOR PRIORITY: keep the font's own colors if specified; otherwise electric blue, hot pink, acid green or golden yellow neon. Square 1:1 neon sign scene. HAPPY BIRTHDAY rendered as authentic glass neon tube lettering across two lines — HAPPY above, BIRTHDAY below, with BIRTHDAY line slightly larger for typographic weight contrast. Tubes in hot pink and acid green, alternating per line, each with visible glass curvature, hairline electrode end caps, and subtle tube connector bridges. Wide soft bloom radiates outward from both lines, warm pink and green light halos overlapping at the dividing line creating a coral-yellow bleed zone. Background: aged dark brick wall with faint mortar texture and weathered surface patina, barely lit by the sign's own emission. Lower foreground: wet concrete surface reflecting distorted streaks of pink and green neon — elongated mirror smears of both colors dissolving downward. Thin atmospheric haze drifts across the mid-plane, diffusing the outer bloom into a dreamy soft corona. Small electrode bulbs glow brighter at each tube terminus. Celebratory back-alley neon sign energy — warm, festive, retro-electric night atmosphere.
