One color for the most present text, and another for the main background. One color for one level of headers, another for another background color (perhaps another block like a header or a sidebar), and so on.

Get a sweet font and you just might have a beautiful website.

As a designer, I wish it was that easy. :)

I think “beautiful website” (or maybe just pretty) is that easy, but if all you’re hiring a designer for is to make something pretty, you shouldn’t be hiring a designer.
