In Minecraft 1.14 19w08a developers have updated several textures for blocks and Mobs. Now we know for sure that in Minecraft PE 1.11 the textures will also be updated to be brighter and more colorful.
Mojang saw that some textures are not combined with other textures and it was decided to slightly change the appearance of the popular blocks and some mobs:
- Emeralds
- Emerald Blocks
- Zombie
- Skeleton Horses
- Grass Blocks
- Snow Layered Blocks
The change in mobs came later with a recent change in 3D animation and the addition of new moving polygons.
As for the blocks, the changes occurred as a result of voting for changes in textures, as well as personal visions of developers to improve the perception of the overall gameplay. Players have made a choice on the most popular - earth block and snow block.
