I'm having a bit of an issue with the forum colors changing. I have changed the default colors to more of a teal/dark teal colors to match my website colors but when I save the colors it doesn't change on the front end of my website. The settings save and everything looks fine from the back end. Am I supposed to change anything else in order for the color changes to show up front end?

Note: I've also tried ticking one of the other color selections without modifying anything and I've had the same issue. Nothing changes front end.
