Abstract Light Art Letter 3 Vertical Stripes AI Image Prompt

This is a futuristic abstract light art image with a vertical stripe composition. On a pure black background, evenly spaced semi-transparent luminous bands use color gradients and light-dark contrast to cleverly form the shape of a capital letter "3". The colors of the bands transition from left to right, starting with deep cobalt blue and cyan, transitioning to warm orange-red and cream white, and then to bright white and gray-black on the right. The dynamic layering of cool and warm colors enhances the contour of the letter. The edges of the bands have soft blur and chromatic dispersion effects, resembling light trails captured in high-speed motion or a visualization of digital signals. The overall style is abstract light art, combining a sense of technology and psychedelia, suitable as a background element for digital art, brand identity, or visual design.
