When I custom set my browser colors, I no longer see the yellow "new" highlighting. Some of the lettering disappears, too, as if taking on the background color. Some examples are the top bar with the Boards | Features | Digest | My CHOW | Getting Started links and the "LATEST POSTS FROM THE BOARDS" header on the Home Page.
My background color is a light grey, and the text and link colors are black, blue and purple (just a little less bright than the default) so it's not from lack of contrast. I haven't had this problem with any other websites.
Is there a way to fix this? I'm using Firefox.
