The Green Grass texture pack makes the grass greener and richer, and the biomes do not eliminate their color, although they make it much brighter than vanilla grass. The foliage also becomes brighter and also does not reveal its color in the last biome. Which makes the world much brighter than vanilla. (This texture package is similar to the texture package for the java version, but more improved).
