An ultra-detailed close-up portrait of a woman with luminous pastel rainbow hair cascading in soft waves. Her skin is flawless, with a radiant glow that catches a prism of light reflecting a rainbow across her collarbone and face. Her eyes, wide and expressive, have multicolored iridescent eyeshadow, and her lips are a soft, natural pink. The lighting softly wraps around her, creating a serene and dreamlike atmosphere with subtle shadows.
