Revlon Radiant is a slightly cool-toned, medium-dark blue with a glitter finish. It is a limited edition nail lacquer that retails for $4.99.
Revlon Radiant (Blue Mosaic) Nail Lacquer ($4.99 for 0.50 fl. oz.) is a blue-tinted clear base with blue glitter and larger green, silver, and blue hexagon-shaped glitter. It totally reminded me of the glitter in Deborah Lippmann--if you used Radiant (Blue Mosaic) over a blue-black base, you'd get pretty close to the overall shade. The major difference is Radiant has a mostly clear base, while Deborah Lippmann is a colored (opaque) base. That would, of course, make Radiant more versatile, since you could layer it over any number of polishes.
A gentle shake of the bottle and two coats and your nails are good to go. From the beach to the boardroom, this formaldehyde and toluene-free nail enamel by Revlon is available in a variety of shades to suit your style.
