The Curtains match the tiles

I snapped this photo because the navy blue curtain is now the same beige as the tiles. But when I returned home and looked at it, I noticed the beige stripe going up the wall on the right. Apparently the mold is not picky: tile or polyester curtain. It knows both places are safe from bleach, scrub brushes, disinfectant, or even the gaze the management's eyes.
