For your gel-x nail design, imagine the cool depths of the ocean meeting a dazzling summer sunset. Use a base of iridescent turquoise, accented with shimmering gold and bright coral strokes, reminiscent of seashore reflections. Incorporate delicate white wave patterns and tiny pastel seashell decals for a playful yet elegant touch. Let each nail be a canvas that echoes the serene undertones of the sea while celebrating the vibrant excitement of a sunset on the horizon.
