Galactic Octagons in Starry Cosmos

A breathtaking galactic scene illustrating a series of radiant, floating octagons in a dark, starry cosmos. These octagons, differing in size, display a range of colors such as emerald, lavender, and crimson, with a glistening, pearlescent quality. Each octagon appears to radiate light from within, enhancing their luminous presence. The background is a deep black with a scattering of stars and bright, multicolored sparkles, contributing to the image's ethereal and otherworldly atmosphere. The style is abstract and imaginative, with a focus on vivid colors and luminous effects.
