Checks for sufficient contrast between text and background colors.
This is a manual check to ensure there is enough contrast between the color of your text and its background color. The standard (WCAG 2.1 AA) requires a contrast ratio of at least 4.5:1 for normal text.
Users with low vision or color blindness may find it difficult or impossible to read text that does not have sufficient contrast with its background.
Poor color contrast can make your content unreadable for a large number of users.
Use an online color contrast checker. Enter your text and background hex codes to see if they pass the accessibility standards. For example, dark grey text (#333333) on a white background (#FFFFFF) has excellent contrast.Run a free audit to see how your site performs on Color Contrast and 159 other checks.
