Does the Black and White combination comply with ADA standards?
Under current ADA Title III guidelines, digital services are audited against WCAG 2.1 level AA. This pairing scores a contrast ratio of 21.00:1. This means it meets the 4.5:1 minimum threshold for body text, and meets the 3.0:1 threshold for large text elements.
What defines large text vs normal text in contrast requirements?
Large text is defined by the W3C as text that is at least 18 point (typically 24px) or 14 point bold (typically 18.67px bold). Normal text is any text below these sizes, requiring a higher minimum contrast ratio of 4.5:1 because smaller font sizes are significantly harder to read at lower contrast.
