I guess it would help to know the demographic that my site appeals to, but being completely new... I have no idea. I would also not dare to make any assumptions, as the internet is very good at grinding those to dust.
The focus point of this forum is going to be consumer related , in terms of new products on the market and people's thoughts on them after buying. Should I try to match the colors used by places like newegg and amazon? I notice that xenforo already is doing that out of the box with the use of oranges, blues, and white. Is there some sort of psychological effect I need to be aware of?
I'm leaning towards a lighter theme, but I'm open to suggestions for both, and the reasoning behind it.
