Color should not be used as the only visual way to convey information or make an indication.
What to do:
- Identify any ways your website conveys information by color and make sure there is another way to extract the same information
Plain English Explanation:
This success criterion attempts to eliminate any circumstances where color alone is used to convey information, make an indication or prompt the user, or distinguish between visual elements.
This error is present much more than you might think.
Examples:
- Toggle switches where green indicates activated or on and gray indicates off
- Required fields are in red
- Color coded graphs and charts
You do not have to eliminate color for information or as an indicator but you do have to account for the fact that some people may not be able to perceive the color and add an alternate means (such as text) where people can gather the same information or indication.
