]What if the image alt text mentions a color that isn’t actually in the image?
If the image alt text mentions a color that isn’t actually in the image, it’s not providing useful information for blind users. To fix this, you should describe the content of the image using the alt text, rather than relying on color. For example, you could say See the red bar on the chart to determine the spike
instead of See the red bar on the chart.
This ensures that all users can understand the content of the image, regardless of their ability to see color.
How to fix it
Determine if the named color does not refer to part of the content that conveys information.
