Photochromic Powder Pigments change color when exposed to Sun/UV light. The pigment is one color indoors, but when you step outside and expose to Sunlight, it turns another color depending on how strong the sun is and how much Ultra Violet light it absorbs. The process is reversible- when you go back indoor or block UV light, the pigment turns back to its original color.

You can mix it with CLEAR or WHITE glues, paint, varnish, resins, silicone, hair gel, liquid soap, plastics/polymers, nail polish and many more mediums depending on what surface you would like to apply on.. The pigment doesnt mix directly with water. Our products can be used for Color Changing Slime, Tumblers, Nail Polish, DIY Color Changing T-Shirts & Shoes, Home & School projects, Science Experiments, Arts & Crafts or wherever your imagination takes you.

Sun Activated Powder Pigments will not react to temperature like our Thermochromic Products and it will not change color by the heat of your hands. It changes color only when exposed to UV Light or Sunlight.
