Encountered with Quark beta 47, Building Bricks 1.10.2-2.0.10, and Forge 12.18.1.2011 (recommended version as of July 25), on Minecraft 1.10.2.

The Greener grass config option does not apply to Building Bricks grass slabs (which are added by Realistic worldgen).

I started a new world with Realistic worldgen, and found some grass slabs. Their coloration does not match the surrounding grass. When I turned off Greener grass, the coloration matched.

This is caused by the name of the block in the config being wrong. It should be buildingbricks:grass_slab instead of buildingbrickscompatvanilla:grass_slab.

(Does GitHub notify on edit, and if not,) is this any better?

It doesn't, so you'll have to bump it like you just did
