Designers must take into consideration the colors they use for the text and the background. There needs to be a significant level of contrast between the two in order to make the text easily readable.

Take a look at this forum page from the Harry Potter Pages website. Notice how the two hues of green have similar levels of brightness. The text does appear darker than the background, but the small difference renders the text difficult to read. Also take notice of what appears below the area circled in red. The same text color is used here, but the background color has been brightened significantly. The text here, though the same level of brightness f the text just above, is easier to read because the background color is brighter (lighter).

Hanson (2004) argues for color/contrast control to be included in software designed to support internet surfing using a standard browser. Hanson (2001) also mentions the difficulty in reading text set upon a background image. To address some of these concerns, the article "Making your Website Senior Friendly" (2002) suggests that designers stay away from using blue, green, and yellow within close promximity of each other. In addition, the article suggests that designers use dark type against light backgrounds or white lettering against dark backgrounds. This recommendation was not followed by the designers of the Harry Potter Pages Forum for the segment circled in red.
