Blue has been and always will be the front line for a summer colour as it relates to bright blue skies & even bluer seas but it is also known the dark beauty inside. With a saturation change, this Summer colour can easily become the darker side with its Navy blue & dark night. The Blue nail polishes are available at Nail Polish Direct to come in an impressive range of finishes, among them gloss, glitter, creme, textured, suede and metallic.
