A UV camouflaging substance, in the form of a solid, powder, paste, film, or liquid, can be applied to objects such as fabrics to match the ultraviolet reflectivity of the objects with their immediate surroundings. Embodiments are transparent to visible and IR light, and can be applied without changing the visible appearance of the objects. Other embodiments visibly match the surrounding environment, such as a white substance used near snow. Different embodiments can be layered on top of each other to form UV camouflage textures and to adapt to changing environments. Some embodiments can be washed off, to avoid a build-up of camouflage layers. Embodiments include UV-interactive micro- or nano-particles suspended in a binding agent which transmit, reflect, absorb and/or scatter ultraviolet rays. Some particles are absorbent, while others are approximately one-quarter wavelength thick, and suppress UV light by inducing half-wavelength phase shifts between light reflected from opposing surfaces.
