Prompt
A starburst-like structure forms a wide radial pattern with long thin filaments extending from a dark circular core. The colors radiate outward in alternating cool and warm segments, creating a symmetrical energy bloom. Tiny sparks scatter along each filament, becoming more sparse near the tips. The background stays deep and quiet, allowing the burst to stand out while leaving the corners clean for design use. Soft ambient highlights emphasize the radial motion, and the center remains slightly recessed to enhance depth. Sharp detail at the core gradually softens outward.
