Neon Sign 7

A neon cross or plus sign symbol rendered with a glowing tube effect against a pure black background. The cross features a bright cyan-blue neon outline (#0033ff) with a secondary lime-green glow (#aeff00) creating a dual-color neon tube appearance. The neon has a characteristic tubular thickness with rounded corners and smooth curves at the intersections. A bright blue glow radiates outward from the neon lines, creating a halo effect with high intensity (1.95). The top-left and bottom-right corners of the cross display curved, organic edges rather than sharp angles, giving it a stylized appearance. Small floating particles with a light-blue tint (#4fadff) drift slowly around the symbol, adding subtle depth and atmosphere. A tilt-shift blur effect is applied with a 70-degree angle, creating a slight depth-of-field effect that enhances the focus on the central cross. The overall mood is modern, digital, and energetic with a cyberpunk aesthetic. The neon flickers subtly with a flickering speed of 1.1 and amount of 0.24, creating a realistic tube light effect. The specular highlights on the neon tube add dimensionality and suggest a three-dimensional glowing object.
