I've merged Bartosz's patch (https://gerrit.wikimedia.org/r/#/c/82828/) for rolling out the boxes to all forms, not just vforms.

He used the same colors as the vform styles.  It seems to me that the success and error boxes might be better with a little more color contrast.

You can test on Beta (http://en.wikipedia.beta.wmflabs.org/) by editing your preferences (success), going to Special:UserLogin while logged in (warning), and entering the wrong password for login (error).

These changes have been backported to the current MediaWiki release, and they're visible on production now, including mobile versions of the examples Matt pointed to above. 

For a bit more background: IIRC Bartosz generated the palette here based on the error message style, which Munaf designed in vform for the login and signup redesign. I agree we should make sure the contrast is enough to meet accessibility guidelines, but the nicest thing about the new styles are that it is more cohesive than previous, and we should make sure to retain that. :)
