I cut the background out of my avatar a few weeks ago, and thought that made it look better on more sites. As of very recently, there seems to be a background color set on avatars as part of the theme on SO and MSO (I believe some other sites already had this). I'd prefer it if they didn't.
Does anyone else have an opinion about this?

On Ask Different the background looks absurd in profiles because it doesn't match the border:
On Cross Validated there's no color I could pick to match the background:
