Elements must meet minimum color contrast ratio thresholds
What is the problem?
The color-contrast rule ensures that the contrast between foreground and background colors is sufficient for readability.
Impacted Groups
Why is this important?
Insufficient color contrast can make text difficult or impossible to read for people with visual impairments, such as those with low vision or color blindness. This can hinder their ability to access and understand information on the website.
How to solve this issue
To address this issue, use a color contrast checker tool to ensure that the color contrast meets WCAG 2 AA minimum contrast ratio thresholds. This can be achieved by using sufficient color contrast, using larger font sizes, or increasing the line spacing.
