Imagine a set of ethereal aura nails that resemble a celestial masterpiece painted onto each fingertip. The design captures the gradient of a mesmerizing sunset, where pink and orange hues gently transition into enchanting purples and blues. Illuminate each nail with an iridescent shimmer that reflects light in unique spectrums as if kissed by the Northern Lights. To enhance the celestial theme, add delicate starry accents and subtle moon charms delicately positioned on select nails. Conclude with a glossy, clear topcoat to seal in the magical effect and provide a brilliant shine.
