a housing for storing and protecting items comprises a photoreactive material that selectively and irreversibly changes colors upon exposure to activating radiation ; and an ultraviolet attenuation coating disposed over the photoreactive material . radiation is selectively applied to the photoreactive material to irreversibly change the color of the photoreactive material and therefore the housing . an optional patterned layer may be disposed between the photoreactive material and the selective application of radiation , and a background color may be included , to affect the visual presentation of the housing .
