The hex color #28509E, also known as Sapphire, presents specific accessibility considerations for web development. Its relatively low lightness value means it requires careful pairing with text and other interactive elements to ensure sufficient contrast. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). When using Sapphire for backgrounds, it's crucial to use light-colored text. White text (#FFFFFF) is generally a safe choice, but it's essential to verify the contrast ratio using an online contrast checker. Conversely, using dark text colors like black (#000000) is strongly discouraged due to insufficient contrast. Ensure that interactive elements like buttons and links using Sapphire are clearly distinguishable from surrounding content, both visually and programmatically. This can be achieved through the use of borders, underlines, or changes in color upon hover or focus. Always test color combinations with users, especially those with visual impairments, to validate accessibility.
