The hex color #1A4B81, also known as Chathams Blue, presents some accessibility challenges. Its relatively low luminance contrast against a white background can make text difficult to read for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This color falls short of those recommendations and thus should be carefully considered. To improve accessibility, consider pairing it with lighter colors for text and interactive elements. Providing sufficient contrast ensures that all users, including those with low vision or color blindness, can easily perceive and interact with the content. Testing with accessibility tools is highly recommended.
