People who cannot differentiate between certain colors, and those using monochrome displays and printers, may not be able to see information conveyed solely with color. For example, if red is used as the sole means of denoting high priority content then people with color-blindness may not be able to identify high priority content.
The purpose of this checkpoint is to identify any information that is conveyed solely through the use of color and ensure there is an alternate way to convey this information.
- Click Show Filter to display a filter that removes color.
- Drag the filter over the slide to identify any information that is conveyed solely through color (example: charts where color is the only means of identifying distinct data sets).
- If you find information that is conveyed solely through color, stop working in CommonLook Office and update the presentation to provide all information without color or to ensure such information is also conveyed using other means (example: textual description).
- Click Next to continue.
