Editing Paint

Huey's capacity is indicated with a paint meter, featuring three columns for each primary color of red, blue, and yellow. Secondary colors are used by combining these paint reserves (e.g. green paint requires both blue and yellow paint). The meters can be filled by blobs of paint acquired from environmental objects, dropped from defeated enemies, wrung out from squeezing [[Thing Card|Things]], or simply found on the ground, and paint capacity can be increased by collecting [[Hammer Scrap]]s. Paint blobs vary in size and color, shimmering every 1.5 seconds. Using a [[1-Up Mushroom]] card in battle or drinking either [[Prisma Juice]] or [[Mustard Juice]] will fully restore Mario's paint, whilst stepping into the rainbow paint of Prisma Fountain restores both Mario's paint and [[HP]].

In battles, paint increases the strength of [[Battle Card (Paper Mario: Color Splash)|Battle Card]]s, similar to using [[Flower Point]]s for stronger attacks. Each card requires specific amounts and colors of paint to be used at full strength, but an unfinished or even uncolored card still has minimal effect in battle. Paint also indicates the amount of [[HP]] each enemy has left, where more damage results in the enemy being further drained of color starting at their feet. This replaces the typical health-bar indicator used in previous ''Paper Mario'' entries. [[Roy|Roy Koopa]] uses paint stolen from Mario in his battle to inflict status effects:

The Big Paint Stars reveal that paint has the power to communicate thoughts and memories between individuals telepathically, as demonstrated when Mario and Huey are shown the events that resulted in Port Prisma's attack. Paint is also consumed when pressing {{button|wiiu|y}} to [[Flip]], a technique used inside the [[Green Energy Plant]] monitor to navigate the ''[[Super Mario Bros. 3]]''-inspired locations with a 3D, isometric view. Additionally, the map used to navigate between areas of the island is initially devoid of color. As [[Mini Paint Star]]s are collected, more areas are filled in with paint both to indicate that new levels are accessible and serve as a visual aide towards the progress of repainting Prisma Island.
