Accidentally changed a setting on phone?

I accidentally unlocked my phone in my pocket and pushed a bunch of things. Somehow this resulted in the themes?for Facebook and Safari to look different. The google search results and Facebook comments (on the app) in particular look different (Google looks lighter blue and a different font: first pic- google search result in safari, Facebook comments look like messages).. I've checked with several of my friends and they're apps have not changed. I also hard reset my phone and it's still like that. Also the Google searches on private browsing look like normal.
