Feature: This Pigment changes colors when exposed to Sunlight or UV light, and reverts to its original color when sunlight is blocked. The pigment is WHITE indoors, but when you move it outdoor and expose to Sunlight, it turns to your color depending on how strong the for 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- WHITE. It could be mixed with materials such as glues, paint, varnishes, resins, mediums, gels, liquid plastics/polymers, nail polish and many more. The pigment doesn'for t mix with water.
