The color #1A507E, also known as Chathams Blue, presents some accessibility challenges, particularly for users with visual impairments. Its relatively low luminance value of approximately 0.1 means that text rendered in this color on a white background may not meet the WCAG (Web Content Accessibility Guidelines) requirements for contrast ratio. Specifically, it falls short of the minimum 4.5:1 contrast ratio for normal text and 3:1 for large text. To improve accessibility, consider using #1A507E for decorative elements rather than essential text or interactive components. If it must be used for text, pair it with a very light color like white (#FFFFFF) or a bright yellow to ensure sufficient contrast. Tools like contrast checkers can help verify compliance. Additionally, providing alternative visual cues, such as icons or underlines, can assist users who have difficulty distinguishing between colors. When using it in larger UI elements, ensure there are sufficient contrasting borders.
