Beyoncé has tried an array of blue nail polishes lately—from robin's egg to sapphire—which is why we caught up with her manicurist Lisa Logan to get the details on Bey’s favorite hue. “Blue is a great color, and it looks amazing on Beyoncé,” she told InStyle.com exclusively. “We always have a variety to choose from.” So, are her azure lacquers a tribute to her new daughter, Blue Ivy? “That’s up to anyone to decide!” Logan said playfully. “It is a pretty color, though, and Beyoncé wears it well.” Check out four lacquers worn by the star in the gallery, and find out why her manicurist picked each shade.
