The hex color #123d89, also known as Congress Blue, presents some accessibility considerations for web developers. Its relatively low luminance value means that it requires careful attention to color contrast. When used as a background color, it's crucial to pair it with text that is sufficiently light to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Tools like WebAIM's Contrast Checker can be used to verify compliance. Conversely, if #123d89 is used for text, the background must be a very light color. Developers should also consider users with color vision deficiencies and ensure that information is not conveyed solely through color. Providing alternative visual cues or text labels can enhance accessibility for all users. Proper use of ARIA attributes can also further improve accessibility.
