A: Due to the graphical (and colorful) nature of this site, considerations have been made for people who cannot distinguish colors. Despite these efforts, some shades may be somewhat more difficult to distinguish. A Color Blindness Tool can be accessed by clicking here, which may assist in reading the graphics.
