As if spending time in the sun doesn’t make you happy enough, Our Falling Sky color-changing nail polish lives up to its name and will send you to cloud nine. You’re happiness will swell as the glitter polish transforms from turquoise to green when exposed to the sun. Look no farther for bliss in a bottle. It’s safe, too — being 5-Free and never tested on animals. (Formerly known as Del Sol OnCloudNine.)
Much like a flower that blooms when exposed to sunlight, Del Sol's products change colors in the sun using their proprietary Spectrachrome® technology.
Spectrachrome® molecules in the products shift to colors visible to the human eye when exposed to UV sunlight.
Del Sol's Spectrachrome® formula for color change was developed from a concept originally researched by NASA for use in space.
