Many web designers overlook the importance of color when designing a web site.
Color should be one of your first concerns when it comes time to start your web site design. If you don't pay close attention to the colors you chose, your site you will end up either plain and boring or so chaotic it's hard to look at. The color you use should only be chosen after careful consideration. Unfortunately web browsers can only see 256 colors. Even that number is hindered because all browsers don't share the same 256-color pallet.
