Get ready to make everyone whistle in awe. Thistle the Day Away color-changing nail polish is a sky blue indoors but transforms to a rich pink once exposed to sunlight. The polish, inspired by the strong thistle flower, will become your go-to hue. It’s safe, too — being 5-Free and never tested on animals.
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.
