The hex color #013056, a deep shade of Prussian Blue, presents specific accessibility considerations for web design. Its low luminance value results in a poor contrast ratio against standard white backgrounds, potentially causing readability issues for users with visual impairments. To ensure accessibility, it is crucial to pair this color with light text or interface elements. A contrast ratio of at least 4.5:1 is recommended for Level AA compliance under WCAG guidelines, and a 7:1 ratio for Level AAA. Tools like contrast checkers can help verify compliance.

Strategies such as text shadows or background highlights can further enhance legibility when using this deep hue.
