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.
