I found that there's is a graphical Issue with the Leaves since a version of the Nether Update: 1.16.200. if you find about this issue, which is dependent upon what GPU you have. Some are tinted Red, some have a Magenta or Black tint, while the rest are in somewhere in between the components inside the Devices when that installed, regardless from a Biome Blend feature that happens in the Java Edition, on some snapshots and versions which has a Colo(u)r messed up including the Leaves has mentioned, graphical issues on the Frozen or Snow Biomes is still occurred since.

^{as for jeb_,}

Sincerely for you MOJANG.
