General Information about Prussian Blue

Prussian Blue, represented by the hexadecimal color code #063157, is a deep, rich shade of blue known for its historical significance as one of the first synthetically produced pigments.

In digital contexts, #063157 can evoke feelings of trustworthiness, stability, and intelligence.

However, its darkness also means careful attention must be paid to contrast when used with text or other design elements.

The color #063157, a deep shade of Prussian Blue, presents significant accessibility challenges, especially when used as a text color. Its low luminance value means that it requires a very light background to ensure sufficient contrast for readability, adhering to WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When using #063157 for interactive elements like buttons or links, it is crucial to provide clear visual cues beyond just color to ensure usability for users with color vision deficiencies. Furthermore, avoid using this color in complex data visualizations without careful consideration for colorblind users; provide alternative cues such as patterns or labels. Thorough testing with accessibility tools is highly recommended.
