Envision a classic French tip nail design, meticulously modernized by using a chic spectrum of blue hues. Picture each nail adorned with a sleek azure line, elegantly contrasting against a pristine milky base. Try incorporating delicate touches of silver foil to accentuate this sophisticated palette, adding a sprinkle of glam. For a playful twist, include a nail or two with an ombre gradient transitioning from a deep navy to a soft sky blue.
