From what I can see, the colours aren’t that bad – you just haven’t used them! You’ve got Orange, tan, white, grey and black; but at first showing the page only displays white, grey, grey, more grey, blue(?), black (a little bit on the lettering), and yet more grey. The only orange is the RSS button and on hover (using a colour only in a hover state is a waste of a colour, and too late IMHO – the first impression’s already been formed.)
Maybe start with a plain white background without those heavy grey pillars to either side and throw some of those oranges and tans around…
