[UPDATE: NEW COLOURS ADDED!]
The texture pack gives birch leaves an orange colour to reflect real birch trees in autumn and add a bit of colour to your Minecraft world! The change affects birch in all biomes, so you can build using orange leaves anywhere in your world!

Changelog
- added a pink variant of birch leaves
- added a red variant of birch leaves
- changed the colour of the birch sapling to reflect the colour of the leaves
I've added a pink and a red variant for now, but if there's another particular tree variant you want to see, I'll probably prioritize it when deciding what pack to do next.
