G182: Ensuring that additional visual cues are available when text color differences are used to convey information


Colored text when the color is used to convey information such as:

This technique relates to:


The intent of this technique is to provide a redundant visual cue for users who may not be able to discern a difference in text color. Color is commonly used to indicate the different status of words that are part of a paragraph or other block of text or where special characters or graphics cannot be used to indicate which words have special status. For example, scattered words in text may be hypertext links that are marked as such by being printed in a different color. This technique describes a way to provide cues in addition to color so that users who may have difficulty perceiving color differences or have low vision can identify them.

To use this technique, an author incorporates a visual cue in addition to color for each place where color alone is used to convey information. Visual cues can take many forms including changes to the font style, the addition of underlines, bold, or italics, or changes to the font size.

Note: While this technique is sufficient to meet the visual requirements of Success Criterion 1.4.1, the information conveyed by the color must also be available programmatically to satisfy Success Criterion 1.3.1. See How to Meet 1.3.1.




  1. Locate all instances where the color of text is used to convey information.
