Suggestion Ensure parts of graphical objects essential for understanding content have sufficient contrast. The required minimum contrast ratio is 3.00:1.

Common examples of qualifying objects include lines in a chart, meaningful icons, and annotations within an image.

Graphics that require particular presentation to preserve their meaning are exempt from this requirement.
