A downloadable version of FabianPEK's Four-Color deck mod on NexusMods. Just some hastily put together stuff so I could enable/disable the skin in the mod menu. Also added a high-contrast version of the skin, and made it so that the suit text also changes colour.
Extract and place the 'FourColorDeck' folder into the mod folder. (Probably in %appdata%/Balatro/Mods)
