Spectral Wave

Retro digital illustration of a vibrant, undulating sinusoidal rainbow ribbon flowing vertically through deep space, the luminous wave curving gracefully amidst a dense field of tiny, multicolored stars. The mood is nostalgic and psychedelic, captured in a flat graphic composition with centered framing. Self-illuminated with a soft chromatic glow, the saturated spectrum of red, yellow, green, and blue pops against a pitch-black background, textured with heavy analog film grain, gritty noise, and a vintage risograph print finish.
