WCAG stands for Web Content Accessibility Guidelines. These are a set of international standards for making web content more accessible to people with disabilities.

Why is color contrast important?

Adequate color contrast is essential for readability, especially for users with low vision or color blindness. It ensures that text is distinguishable from the background.

What is the difference between AA and AAA compliance?

AA compliance is the standard level of accessibility, requiring a contrast ratio of 4.5:1 for normal text and 3:1 for large text. AAA compliance is a higher level, requiring 7:1 for normal text and 4.5:1 for large text.

Understanding Color Contrast

Color contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In web accessibility, adequate contrast between text and background is crucial for users with low vision or color blindness.

WCAG Standards

The Web Content Accessibility Guidelines (WCAG) define specific contrast ratio requirements for different levels of conformance:

AA: Requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text.
AAA: Requires a contrast ratio of at least 7:1 for normal text and 4.5:1 for large text.
