Ok, after failing a thousand times over on disecting the meaning of the default set-up theme for buddypress, I downloaded another one. Then, I dissected it and redid the colors. Thus, here we are.
Maybe it’s not fully to the standards where I would like it, but at least now it looks harmonious with the rest of the content on my site namely the forums.
So, yay. Hard work and not really wanting to build a theme from scratch paid off.
