Blue implies authority, financial responsibility, and security. Green means health and tranquillity. Blue is the most popular color. The style of your Web site should be consistent from page to page. Select a background and colors, then stick with them.
Web pages comes in one, two, or three columns.
Ninety percent of the time, a two column format works best. This is where you put your table of contents, or listings. Use the rest to put your text, headlines, banner ads, and key offers. Most of all, don't change your formatting from page to page. Use the same colors and standard look so people don't think about where things are.
