These backgrounds may look like they are just plain colors but they are not. On a good
monitor, they should look slightly ruffled. Viewers with different monitors may experience these backgrounds
slightly different. Lower quality video cards and monitors can affect the overall perceived quality of your
web pages. One should not only test web pages using different browsers but also different computer
systems if possible.
Such web page backgrounds need testing too to see what color and font sizes easily show up. If one uses a dark
colored font on a dark background, it may be difficult with some computer systems to distinguish the text.
