The color contrast overlay evaluates difficulties that users might encounter when they view items on a website due to a lack of contrast between the foreground text and the background color. The overlay shows violations of WCAG2.0 standards and determines where the contrast issue is located.

Depending on the number or location of the severity icons, it can be difficult to analyze data. You can click and drag any severity icon to a new location on the screen. An indicator line ties the severity icon to the object.

A contrast ratio of 4.5 or greater is necessary to avoid being pinpointed as a violation by the Color Contrast overlay.
