There's no blue or grey automatic background for posts of moderators and developers now. At least it is how I've started to see it today using Chrome on Windows.
We're all equal now before the eye of the beholder.
Blue posts have gradients but moderator posts don't (blue posts and moderator posts both have the correct colour background though). it would be nice if quote boxes in comments contrasted better against the rest of the comment. The quote box is virtually indistinguishable in this @Tresset post for example: https://forums.beamdog.com/discussion/comment/725430/#Comment_725430

(~me chromy too~)
But only in comments. If it is the OP of a discussion the gradient is still there.
