Suspend the cap on an invisible platform against a deep space background filled with stars, distant galaxies, and nebula clouds in deep purples, blues, and teals. Create dramatic rim lighting from an unseen cosmic light source, making the cap appear to float in zero gravity. Add subtle lens flares and light particles drifting through space. The surface beneath shows reflective properties like liquid mercury or crystalline material. Atmosphere is ethereal and otherworldly with deep contrast and mystical color grading.
