Well, I did try to warn about that in the PR:

Note that some colors and padding was changed, to match Foundation for Sites. If these colors where different by purpose then we need to edit the pull request (or make a new one).

@Aetles I did see your warning, so right away I knew what the problem was. Was just getting things back to where they were. Thanks!
