Imagining a starlit night sky, create a dazzling set of blue nails that evoke the mystical beauty of twilight. Incorporate gradients that blend deep midnight blue into lighter celestial hues. Highlight the nails with shimmering specks reminiscent of constellations, using tiny, glistening rhinestones or glitter for added sparkle. Allow some nails to feature delicate silver streaks that mimic shooting stars, bringing a serene and magical aura to the design.
