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. Square composition. Render the exact text ":(" as a small, solitary roadside neon sign, centered with generous dark negative space around it. The two characters glow in dim, cold blue glass tubing, with a faint icy-white core and a restrained blue halo that fades quickly into darkness. Make the bent glass tubes and their tiny support clips visible against a narrow, weathered black metal backing plate; the colon’s two dots are separate glowing glass loops, and the curved parenthesis remains unmistakably legible. Mount the plate on an old rain-dark brick wall, its charcoal mortar and uneven wet brick catching only a trace of blue light. Fine rain beads cling to the metal and shimmer along the brick edges. Below, a thin strip of wet pavement reflects a broken, wavering blue streak. Keep the surrounding setting nearly black and empty, with no people, extra lettering, symbols, or bright ambient light. The sign feels lonely and quietly sorrowful rather than dramatic: cold light, soft glass bloom, deep shadows, subdued contrast, and a fragile glow suspended in the night.
