A UV activated shirt changes color in response to sunlight exposure because the special dye in the fabric reacts to ultraviolet (UV) light. When the shirt is exposed to sunlight, the UV rays cause the dye molecules to change structure, which results in a color change. This process is reversible, meaning the shirt will return to its original color when no longer exposed to UV light.
