Craft a stunning cat eye nail design that embodies the mysterious allure and playful elegance of feline grace. Incorporate a dazzling effect that mimics the shimmering reflection in a cat's eye, using rich, velvety tones that blend seamlessly from base to tip. Enhance the design with subtle undercurrents of iridescent blues and greens, creating a holographic spectrum across each nail. Finish with a glossy coat that not only enhances the enchanting effects but also magnifies the depth and dimension of the colors.
