The theme is modern looking but black is associated with black hat with web development - but it's not a black hat forum.
I actually don't really associate 'black' with 'black hat' - why do you feel like that? It's usually nice if a forum has a dark theme (next to a light theme, because I personally prefer light themes) simply because it's easier on the eyes during nighttime.
If you're not a huge fan of dark themes, why don't you go for a mixed theme (light content area, dark background colour)?
Also, I actually do not really see why this should be considered 'news'. There is literally zero activity on the forum. Plus, the theme is just a free theme - which doesn't matter and could be a nice addition if there would be any activity at all - but nobody actually benefits from this now so I don't think the 'update' all that interesting right now. You should try and get some conversations started on that forum.
