Colorless spots are areas in Paper Mario: Color Splash that have been deprived of color. Every level (besides Black Bowser's Castle and the Roshambo Temples) has colorless spots that Mario can fill in with his Paint Hammer. There are 927 in total. The percentage of colorless spots that have been painted in a level can be seen on the map, and if Mario paints every spot in a level, it gains a gold flag next to its level marker and its record becomes available in the Prisma Museum. A Super Flag is awarded for repainting every colorless spot. Their role is superseded by Not-Bottomless Holes in Paper Mario: The Origami King.
The Shy Bandit appears on the map randomly, and can suck all the color out of a level, besides colorless spots on Toads and spots that are painted in by the Big Paint Stars. If Mario does not catch the Shy Bandit in time, that level's colorless spots must be painted in again.
