1. A stretchable reflective color-shifting film comprising:
a stretchable transparent polymer layer;
a semi-transmissive metal layer;
a transparent spacer layer;
a reflective metal layer;
an adhesive layer; and
a stretchable base film layer;
wherein when the film body is stretched by 25%, the peak total reflectance when stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test, wherein when the film body is stretched by 25%, the peak specular reflection is at least 30% at a normal angle.
