I actually think the foreground is as much to blame for the horrible Beth site - crappy layout all around really, and a poor choice of forum software. Definitely not something they’ve spent any real time on putting together, and I’m sure one the place started filling up with posts from disgruntled customers, that they lost any remaining interest in making it look nice 
I heard about this study of readability, and it’s quite the opposite for me - nothing is as clear as black text on a light background. The opposite starts to give me a headache after a while - when I ran forums I had constant disagreements about theme colours, because I wanted a standard but a handful of users wanted evil dark colours
