Use more than one method to convey your information

Colorblind visitors to a site can become confused or miss important information if it is conveyed only through color. While color‐coding helps some individuals, you must also convey the information without the color‐coding.

Using a set of colors plus icons (as shown in Figure 9-2 ) can be a way to ensure a good experience for a wider audience. Many people benefit from visual cues, so don't avoid them in favor of designing for those who don't; just make sure you use more than one method to convey your information. Using layout and groupings to signal that information belongs together is also useful. Even a well‐planned, color‐coding and icon scheme won't save a page that has a poor layout.

Figure 9-2: Icons can enhance a site for people, whether they have issues with colors.
