Karambit
This is not a biome modification - no new tree generation has been implemented. Almost all content (99%) consists of a resource pack; the only "mod" mechanic is the reworking of pink wood. Details below.

Wood Changes
Changes were made in the following order:
- Bamboo: Green hue removed to match real bamboo plank colors.
- Mangrove: Now orange to match real mangrove in nature (only the bark is red).
- Bulnesia: Replaces acacia. Since mangrove is now orange, this change provides variety.
- Purpleheart: Replaces cherry in the overworld. See rosewater section for details.
- Crimson: Truly red.
- Rosewater: Former cherry. Obtained by cooling crimson wood (right-click in water).
- Malachite: Replaces warped wood only in name.
- Azurite: Completely new wood set. Obtained by cooling malachite in water.
Compatibility
Although the mod remains fully functional, it wasn't designed for backward compatibility with already created worlds. Purpleheart and bulnesia WILL DEFINITELY replace your cherry and acacia builds. If you're okay with this, you can use it in your older worlds - it won't break anything.
