The hex color #304CA6, also known as Sapphire, presents some accessibility challenges, particularly for text-based content. Its relatively low luminance contrasts significantly with both white and black backgrounds. When used as a text color on a white background, the contrast ratio may fall below the WCAG (Web Content Accessibility Guidelines) recommended levels for readability, especially for users with visual impairments. Similarly, using white text on a #304CA6 background could also present readability issues. To ensure accessibility, web developers should carefully evaluate the contrast ratio using online tools and consider pairing #304CA6 with lighter shades for backgrounds and brighter shades for text, or vice-versa. Larger text sizes (18pt or 14pt bold) generally require lower contrast ratios to remain readable. Using this color in decorative elements where readability is not critical poses fewer accessibility concerns. Semantic HTML and ARIA roles should still be used to provide proper context for users of assistive technology, irrespective of color choices.
