The orange Acacia made me need to put eye drops in because it was not aesthetically pleasing. I have made instead a mahogany-inspired wood that should suit the Savannah better while not divorcing itself too much from the reddish Acacia feel. I made the doors and the trapdoors myself though, and for those I make no excuses for my terror. Eh, it's not like you use Acacia doors and trapdoors anyway or you would not be wanting this pack.

The leaves are green but the biome shaders seem to override the leaves' coloring. You would probably need to disable biome shading in a savannah to make the leaves truly look green like a real acacia or mahogany.
