Hide & Seek lives up to its name. It goes on clear, but turns to apple candy red when exposed to sunlight. It’s safe, too — being 5-Free and never tested on animals. (Formerly known as Del Sol Peek-a-Boo.)
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.
