leaf variations for all biomes 🍃

(Only for those with their own trees) Since the autumn biome introduced a new generation of leaves, I think something similar could be done for the other biomes. They could be divided into three phases: we would have lighter leaves, normal ones (the ones already in the game), and slightly darker ones. For example, take a pink leaf: there would be the standard color, a lighter version with tones leaning towards white, and a version with a darker palette featuring a deeper pink. Why include this? Because it would triple the decoration options using these leaves, while also making the world richer in detail =D Please do this!
