Cotton candy nail polish is a shimmery or ultra-glossy nail polish that comes in a light or medium pink shade reminiscent of the color of cotton candy. Cotton candy nail polishes are also available in shades of blue from some manufacturers.
Brands of cotton candy-colored nail polish include OPI and Barielle. Barielle makes a blue cotton candy nail polish that has a silver tint to it. OPI's Coney Island Cotton Candy is a sheer pink shade that gives the nails a hint of color. The Nicole edition of OPI nail polishes features a nail polish called Carnival Cotton Candy, which is darker than Coney Island Cotton Candy.
