Personally I hate ads. I dislike the colour of the forum a little too. it would be nicer if you also have a banner to match with the forum colour.
I agree previous post about colours. Red text in blue background Ligh green text in light blue background I couldn't read those so clear. Dark red in light blue is good.
You should use colours from your banner in template like wumingsden wrote. Black background, yellow text, white links and orange headers, or something else.
