This seems cool!
Say, if you are demotivated with the new overall look, why don't you develop a no-nonsense business like look, then iteratively modify the look after checking with members or friends/collegeagues?
Grey/silver seems modern these days. Important to me is that adds don't distract students.
Orange, purple, green, yellow, these are typical colors that cause controverse it seems.
As soon as you become full of fantasy, you'll find half of the visitors extremely positive, the other extremely negative. No one would be neutral. That's why I would choose for a more business like setup. To avoid controversy. Remember that the speed of this forum (and the informal talk) is your best product.
How about a new try huh?
Below is a sample of this Grey/Silver look I had in mind. Just to get you started. I've "borrowed" it from a gaming clan I communicate with as well. Their leader is a backstabber so who cares
