HI neon outline on dark matte background

The composition centers the letters "HI" in a vertical 9:16 frame with a tight portrait crop that leaves generous negative space above and below for balanced breathing room against the matte field. The lettering reads "HI" in a thin neon outline that is legible from a moderate distance, centered, slightly above true middle, with even spacing and a narrow counter to emphasize air between strokes. The outline material reads like glass tube light with a subtle inner glow in cyan and magenta and a faint outer halo that echoes periwinkle highlights against deep charcoal. The background is a smooth matte dark surface that absorbs reflections and presents soft gradations of charcoal and violet near the edges to frame the letters. The focus resolves crisply on the neon outline with shallow separation so the glow and edge crispness are distinct while the background stays gently soft. The light is cool with warm accents, producing a luminous edge and gentle bloom that sculpts form and suggests slight atmospheric haze. The scene feels minimal and cinematic, suited for poster, signage, or brand display, rendered as a clean photographic-style image with precise contrast and tactile matte texture.
