Create a wide 16:9 horizontal neon wall sign, photographed straight-on. The entire composition is a single finished sign reading “GOOD TIMES ONLY” in three centered lines: “GOOD” / “TIMES” / “ONLY”. The words fill 78% of the sign width and 58% of its height, with generous black negative space around them. Headline lettering: bold rounded display characters made from one continuous bent neon-glass tube per glyph, tube diameter 12% of cap height, rounded joins and terminals, even open spacing. Every individual letter contains its own complete vertical ROYGBIV spectrum: vivid red plasma along the top, orange beneath it, yellow and green at the midline, blue and indigo lower down, saturated violet at the bottom. Do not assign single colors to letters; every glyph must independently show the full rainbow from top to bottom. Glass physics: sharp white specular along the upper outer curve, thin transparent glass edge, darker interior channel, luminous plasma core, ray-traced 1/r-squared colored glow falloff. Mount the tubes on a glossy deep-black smoked acrylic rectangular signboard with rounded corners, subtly visible clear mounting clips and four polished chrome standoff bolts. Background is a near-black charcoal brick wall, softly visible only where rainbow light strikes it. Strong rainbow halos pool behind each line, with sparse tiny red-orange-yellow-green-blue-violet bokeh pinpoints near the outer edges; no extra words, logos, or symbols. High contrast, clean front-facing product photography, crisp tube edges, controlled bloom, deep blacks, 8k render.
