You may have had trouble viewing the text on the last page against the background color. A user with dyslexia, color-blindness, or a visual impairment may have had even more trouble viewing the text on that page. This is important to consider in the design of your own pages especially if you are designing materials for a wide audience. A user who cannot change the color options on their particular browser (or who does not know how) may become extremely frustrated and leave your site before gaining access to the valuable information that you wish to convey.
