New grey background?

When I was posting this morning the post I read had black backgrounds and grey letters. Now the font is black and the background is grey. Don’t know if I accidentally changed it somehow, couldn’t find a way to fix it in my account options. Is there a setting for this? Can I fix it or is it a new look for the site?

Very top of the screen, there is a toolbar with Premium Video, Gear, PodCasts, etc.

There should be a "go dark" button on the end....click that and it will go back to dark.

Above the ATS banner there's an option to either go light or go dark. Mine says go light right now and I have the grey back ground with lighter grey text. Check and see if changing that fixes the problem. Mine got changed on it's own not too long ago and it took me forever to see that little button to fix it.

Thanks both of you. Tried to search for answers and nothing came up, was driving me nuts.
