Black Grass and Leaves in the Nether

Leaves and grass from the overworld when placed in the nether become black, instead of light brownish green color. This will give a different and dark vibe when trees are grown in the nether. It will also give builders a new type of foliage to work with and patches of grass block with tall grass and wither roses should be found in the nether wastelands and Basalt deltas showing that plants that grew here died and burnt due to drought and volcanic activity.
