FYI, Monifactory includes the Quark mod with the "Greener Grass" config setting enabled - I suspect that might be the cause of the color difference?
Quark has a config setting for which blocks is should apply this color change to - maybe this can be "fixed" by adding grass slabs to quark's config file?
