I realy like the greener grass option, and it makes most biomes look nicer. The only exception I could find is with the ominous woods biome from BoP. It makes the grass green. As stupid and logical as it sounds. However it does quite break the ominious visuals. I don't know how the mod makes grass greener, but perhaps if possible exclude this biome colour from becoming greener?
I can always turn the config off, I know. But if I can have the best of both worlds it would be nice.

This isn't really doable, because of the fade effect.
