Futuristic Abstract Light Art FIRST AI Image Prompt

An abstract light art image with a futuristic feel, using vertical stripe composition. On a pure black background, equally spaced semi-transparent glowing bands form the shape of the uppercase letters "FiRST" through color gradients and contrast. The colors of the bands transition from left to right, from deep cobalt blue and cyan to warm orange-red and cream white, then to bright white and gray-black on the right, with interweaving warm and cool dynamic color layers enhancing the letter contours. The edges of the bands have soft blur and dispersion effects, like light trails captured in high-speed motion or a visualization of digital signals. The overall style is abstract light art (ABSTRACTLIGHT ART), combining a sense of technology and psychedelia, suitable as a background element for digital art, brand identity, or visual design. At the bottom of the image, very small text reads "一 x1xxx 一".
