Normal SF&F tags are all one color (blue with a lighter blue background):

But META.SF&F tags are all over the place:

What do the different colors (text and background) mean?

    Dark grey is one of the four compulsory tags that have to be on every Meta question. Red is a special tag that can only be applied by diamonds, IIRC, [featured] is the most notable example of that.

    Strange; your images show a difference in colour between the featured and faq tags, which I can't see when looking at the tags on my screen. AFAIK, the only differences in colour are those described by Alex.

  • @Rand al'Thor: They have very slightly different background colours (not sure if that is intentional), but I doubt they can be distinguished if not right next to each other. For the screenshot above, I suspect the pointer might have been hovering over featured when it was taken.

  • As a note, there's a key at the bottom of the tags page.

Looking at the legend on the /tags page, we see the following key:

  • [red: moderator-only-tag]

    this is a moderator tag, it can only be added by a diamond moderator.

    This includes tags like “faq”, any “status-XYZ” on feature requests and “community-ads”.

  • [dark grey: required-tag]

    this is a required tag; every new question must have at least one required tag.

    Namely “discussion”, “bug”, “feature request” and “support”.

  • [light grey: tag]

    this is a standard tag; every question must have at least one tag.

    These are analogous to the tags on SFF.se – they can be created, added and removed by any user (subject to rep requirements around tags/editing).
