Different categories (that you call forums) can have different colors. I don’t know if they were assigned according to some schema or what. Typically you’ll make each one a different color so that (if you’re not color blind) you can use the color as well as the words to tell things apart.
If you want my help on things like that you’ll need to provide links (which are better than pictures) to the posts in question.
That said, Dog thread .... join up and post about mans best friend here! - #10 by Dcr5595 works, oh but Dog thread .... join up and post about mans best friend here! - #12 by signal4l does not. That’s one of the things that I was going to fix if I had done the migration to Discourse, but someone else did it. It’ll be hard to fix those, but it’s possible.
And those pages aren’t loading for me now.
Does anyone else have an issue where after you load a few pages the site refuses to load any more? Often after I load several pages, especially in a new tab, the site stops responding.
