UV color changing vinyl is white when it is inside or dark, and changes to a new color when it is in the sunlight. The color changes within a few seconds. When taken back inside out of the sun, it will return to the white color. UV lights are also available for purchase separately. The UV lights work with the glow in the dark and also some of the colors of the UV vinyl. You can use them to “draw” on the vinyl, which makes this a fun vinyl for kids. Once the vinyl is drawn on by squeezing the light and touching the vinyl with it, the picture slowly fades away. Within 10 to 30 seconds (depending on the vinyl) the image will disappear. The purple, green, and blue work with the UV lights. The berry, orange, and yellow do NOT change color with UV lights.
