rendered as a classic roadside neon sign with warm glowing tube light in soft pink and amber. Visible glass tube bends and mounting brackets on a dark painted metal backing plate. Warm light halo and bloom around each letter, slight buzzing energy feel. 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-tube sign material, the warm halo and the color. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as a classic roadside neon sign — warm glowing tubes on a dark painted metal backing plate with visible bends and mounting brackets. COLOR PRIORITY: keep the font's own colors if specified; otherwise soft pink and amber. "Feliz cumple" rendered as a physically installed classic roadside neon sign on a rain-darkened midnight brick wall outside a small neighborhood celebration venue. Warm soft-pink glass tubes form the hero lettering, with intermittent amber tube sections and a white-hot inner core; visible curved tube bends, electrode caps, thin metal support brackets, clear insulated wiring, and a charcoal painted-steel backing plate bolted directly into aged red-brown brick. The lettering emits dense optical bloom and a broad coral-and-gold halo across damp mortar lines, while cool blue-black ambient night light remains in the recessed brick texture. Fine rain beads cling to the glass tubing and streak down the backing plate. Below, wet pavement catches broken reflections of pink, amber, and pale orange light, disturbed by shallow puddle ripples. A few restrained party details inhabit the real environment: faded metallic streamers caught against the wall, small water-speckled balloons at the edge of the sign, and scattered confetti glinting in reflected neon. Gentle steam drifts through the lower scene, diffusing the glow. Photorealistic nighttime Americana signage photography, high contrast exposure, ray-traced glass reflections, authentic neon tube illumination, deep shadow detail, no floating text, no digital glow effects.
