One thing to remember is not only how the page looks, but how it prints. With most printers and drivers, the background color won't print. If your web page has gold text and graphics on a black background, what will print out is a page of gold text on a white background (the paper), which might not be easy to read.
You could get around this by having a link to a "printable" page having dark colored text on a light background. More work for your web designers!
On the other hand, black text and graphics on a gold background usually makes for easier viewing, especially if you have a lot of text or detail. Or you could put black and gold text and graphics on a light colored page.
All this is assuming that your team chooses these colors. But the printing issue can be a problem with any light-colored text.
