Envision a serene bubble bath experience encapsulated in a nail design. Start with a base of soft pastel colors, reminiscent of a soothing soap suds scene. Incorporate gentle swirls of pearlescent whites and iridescent glitters that mimic the light, airy bubbles. Add subtle hints of blue and lavender to evoke the calming ambiance of a spa retreat. Finish with accent gems to represent the shimmery droplets from the surface of water.
