A photochromic/vitroceramic window assembly that restores some of the natural illumination and warm blue-green colors normally excluded from the interior of an enclosed space after blocking at least a portion of infrared and/or UV light, comprising : a) A transparent window pane; b) a first self-adhesive material adhered to the exterior of the window pane, of a transparent plastic film containing a UV-activated photochromic dye; andc) a second self-adhesive material adhered to the interior of the window pane, of a transparent plastic film containing i) a rare earth doped vitroceramic that up-converts any infrared not blocked by the first self-adhesive film to a warm visible blue or green color, and ii) a diarylethene that converts any UV not blocked by the first self-adhesive film to a visible yellow-white color.
