The hex color #003459, also known as Prussian Blue, presents some accessibility challenges due to its low luminance. When used as a background color, it necessitates very light text (white or near-white) to ensure sufficient contrast for readability, complying with WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Avoid pairing it with dark or muted colors, as this can cause visual strain, especially for users with visual impairments. When using this color for interactive elements, consider providing additional cues like borders or icons to enhance usability.
