ChrisFurry's animated skin color lua, I've taken a handful of the game's base palettes (Red, Tangerine, Gold, Green, Sapphire, Violet, Taffy, Brown, White, Grey, and Black) as well as my own custom colors from this pack (not including the palettes from my character pack) and made some snazzy animated palettes so you can do your best impression of a neon sign.
Comes in two varieties. "Shiny" (flashes brightly, as shown by the blue/Sapphire Gutbuster) and "Wavy" (transitions through the entire palette, as shown by the warm-colored/Chilli Gutbuster.) Also added a couple bonus palettes (Holly Jolly, which replaces the old Holly and Jolly palettes, and a Shiny-adjacent palette called 'Merica which you can probably guess which colors it goes through.
Note: For whatever reason, you can only load one file of animated palettes. Subsequent files won't load the colors if they're loaded after a file with animated palettes, so take a look through the Animated Palettes zip folder and pick out what suits your needs;
