Chat Box Color

Hello all, It's been a few months since I last logged in to Roll20, but I've offered to run an intro game for a few newcomers on the community server I'm a part of and I noticed as I was logging into the game that my chat box is pink. What's up with this? Is it a new feature? How do I turn it off and go back to the old-school white chat box? Is it maybe because of a browser extension I have that's messing with Roll20 settings?

There was a change a few months ago which made the initial instructions section a pinkish color instead of a greenish color, as well as a change for whispered text from yellow background to green. There isn't a way to change the colors directly, but you can recolor them locally with the Stylish plugin. 

If it is what The Aaron said (the pink instructions section), then simply type several lines in the Chat and it will scroll up and away.  If you mean the text-input box for chat is pink, it shouldn't be, so try disabling your extensions and reload Roll20.
