WCAG Guidelines

The Web Content Accessibility Guidelines (WCAG) specifies different minimum contrast ratios for normal text and large text. Normal text, which is text smaller than 18pt or 14pt bold, requires a minimum contrast ratio of 4.5:1. Large text, intended for users with low vision, should have a minimum contrast ratio of 3:1. These criteria contribute to improved legibility and readability, making content accessible to a broader audience.
