Neon Sign 8

A neon cross or plus sign symbol rendered with a glowing tube-like effect against a pure black background. The cross features a bright cyan-blue neon outline (#7a9cbf primary color with #8fb8d4 glow) with smooth, rounded corners and curved edges that give it an organic, slightly beveled appearance. The neon has a characteristic tube thickness of approximately 0.29 units with intense glow radiating outward, creating a soft halo effect around the geometric shape. The glow color is a lighter blue (#8fb8d4) that bleeds into the darkness. Small floating particles (#c4d8e8 light blue) drift slowly across the scene at an 81-degree angle, adding subtle depth and atmosphere. A tilt-shift blur effect is applied at a 70-degree angle with 80% intensity, creating a shallow depth-of-field that slightly softens the overall image. The secondary color (#b48ea8 muted purple-pink) blends subtly into the neon, adding warmth to the cool blue tones. The entire composition sits on a near-opaque black solid color layer (95% opacity) that creates a dark, moody atmosphere. The neon exhibits realistic tube characteristics including specular highlights, hot core intensity, and a flickering effect with 0.24 amplitude, giving it an authentic vintage neon sign appearance. The cross shape is centered in the frame with perfect symmetry.
