Biome Tinted Flowers
This client-side mod introduces a new visual feature to Minecraft — flowers now receive coloring that matches the biome, similar to how grass and leaves do. This allows plants to blend organically into the environment regardless of location.
For resource pack developers, an example of compatibility implementation is available: https://github.com/Hecco56/Biome-Tinted-Flowers/tree/1.20.1/Resource%20Pack%20Compat%20Example
