I have a task to redesign a web page, the functionality is simple, but the code is robust. The problem is I think the users will give it a low score due to the blah colors and lack of presentation. I was pressed for time and just focused on the functionality and getting the controls all working on the page as the first priority. 

However, when I gave a demo to my boss, it really didn't impress anyone for the way it looked visually. At the time I didn't even have a company logo to add in, so it's really sparse looking.

What are some of the most important visual indicators to give a web page a good presentation of the content? Especially without going overboard and having the presentation interfere with the UI. My first thought was use more colors, but I've seen pages with too many colors and it really is discomforting to my eyes.

I would think another way to word this, is how to balance form versus function in web design.
