Since Reforged graphics, map designers won't be able to use the Ashenvale Canopy Tree as a tree wall that can obscure paths in Lordaeron Summer and Village tilesets, or at least using tree walls from those tilesets, with the green-to-purple ombré color scheme. A friend of mine, @Vibe, has helped me by making a color edit of the main diffuse of the canopy tree model. I further edited the retexture by adjusting the color of the wood to a more warm brown color. Please note that this will replace the diffuse of the Ashenvale Canopy Tree so you don't have to import the variant models of the tree. Just edit the very canopy tree in the World Editor's Object Editor, under the Destructibles category.
I meant the Terrain texture. There is one on the Ashenvale tileset called Leaves, that is leaves on grass. And the leaves there are still purple, so the tileset isn't really useable on any map not set in Ashenvale.
