Ultramarine historically derives from the pigment made by grinding lapis lazuli, a semi-precious stone. This intense blue was highly prized by Renaissance artists. Today, synthetic ultramarine is widely available. The color evokes feelings of depth, stability, and sometimes melancholy. Its darkness requires careful consideration when used in design to ensure sufficient contrast with other elements for readability and accessibility.

The color #030795, a deep ultramarine, presents significant accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text to ensure readability, meeting 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. Failure to meet these ratios can exclude users with visual impairments. Furthermore, avoid using this color as the sole indicator for interactive elements like links or buttons. Supplement it with underlines, borders, or icons to provide alternative cues for users who may not perceive color differences. Thorough testing with color contrast analyzers and user feedback is crucial to guarantee an inclusive design.
