Add saturation to grass

[pasithea2]

Grass looks very dull and unsaturated. Even in the jungle the grass looks dry. I turned my in game brightness down, still looks dull.

Hmm, true, but it's actually a problem in the vanilla textures. I can indeed increase its saturation but that would break texture packs with more vibrant grass. So I'm a bit hesitant about doing it.
