This pack is made for builders who'd like some interior decorations with more character, giving each color of bed a more unique texture and style!
The newest pack version is marked as 1.19. However, it has been tested as far back as 1.13, and appears to work just fine, but will definitely not prior to colored beds being implemented before 17w15a.
IMPORTANT NOTE: As this is just a texture pack for Vanilla Minecraft, the crafting recipe for beds is unchanged.
