Experience Del Sol Color Change 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.
