The color gets its name from the pigment derived from lapis lazuli, a semi-precious stone that was historically imported from overseas ('ultra mare' in Latin).

The color #0F1789, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to comply with WCAG guidelines. It's crucial to test the color combination with accessibility tools to verify sufficient contrast. Using this color for interactive elements, such as links or buttons, also requires careful consideration to ensure they are easily distinguishable. The darkness of the color means that color alone should not be the only method to convey information. Consider adding an icon or text label for additional clarity. Visually impaired users rely on sufficient contrast, and failing to meet accessibility standards can exclude them from accessing content effectively.
