Ultramarine has a long and storied history, dating back to ancient times when it was derived from the precious mineral lapis lazuli.

The color #100C8C, a deep shade of ultramarine, presents some accessibility challenges, especially in web design. When used as a background color, it demands careful consideration of foreground text color. Due to its low lightness value, text needs to have a high contrast ratio to be legible for users with visual impairments. A light color like white or a very bright yellow would be suitable choices to ensure compliance with WCAG guidelines. Conversely, using darker text colors can make the content unreadable for many users. It is crucial to test color combinations with accessibility evaluation tools to ensure sufficient contrast. Furthermore, avoid using this color for essential interactive elements without clear visual cues to avoid accessibility issues for color blind users. The color should be used thoughtfully to create inclusive designs. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is highly recommended.
