This permanent outdoor adhesive vinyl is amazing, with so many uses. If you put this on a glass, car windows or lantern where the light can shine through it turns a bright translucent colour, when the light is off it goes back to it's darker colour. Or if it is on a solid coloured background, the colour remains the same as on the roll. It has a double coloured effect.
The first photo is an example of this vinyl with the light on it, it's bright and vibrant and without the light it is a nice solid colour.
