Why Rogue has white streaks in her hair has no official answer, but in the 2002 movie, the X-men, Rogue (portrayed by Anna Paquin) gets the white streaks in her hair because of a machine built by Magneto that drained her energy, causing some of her hair to turn white. In the animated TV series, X-men: Evolution, Rogue has no back up story about the white streaks in her hair. Some consider the white streaks a sign of Rouges mutation. For example: Mystique's and Nightcrawler's blue skin/furry appearance, Sabertooth's tiger/ lion appearance, Gambit's red eyes, Storm's white hair and blue eyes (that turn white when using powers), Magneto's white hair, are all signs of mutation. The colour of Rogues hair could also have been caused by trauma.
Gypsum streaks typically appear as thin white or light gray streaks on surfaces such as walls or ceilings. These streaks can be caused by water seepage or moisture, which results in the gypsum material absorbing and spreading throughout the surface. To address gypsum streaks, it is important to first identify and fix the source of the moisture to prevent further streaking and damage. Cleaning the affected area with a mild detergent solution and allowing it to dry thoroughly can help remove existing streaks.
To effectively remove water streaks on painted walls, mix equal parts of water and white vinegar in a spray bottle. Spray the solution onto the streaks and gently wipe them away with a clean cloth. Repeat as needed until the streaks are gone.
