Ultramarine, represented by the hexadecimal color code #10188B, is a deep blue pigment derived from the mineral lapis lazuli. Its name originates from the Latin 'ultramarinus', meaning 'beyond the sea', reflecting its historical import from overseas. Chemically, it is a complex sodium aluminosilicate with sulfur. Renowned for its intense and lasting color, Ultramarine has been highly valued since the Middle Ages, often used in religious art to depict the Virgin Mary's robes due to its association with holiness and royalty. In modern color theory, Ultramarine is considered a cool color, evoking feelings of serenity, wisdom, and stability. Its RGB values are R:16, G:24, B:139.

The color #10188B, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio against lighter backgrounds, making text or interactive elements difficult to discern. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. To ensure accessibility, it is recommended to pair Ultramarine with very light colors like white or pale yellow to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using Ultramarine as the sole indicator for interactive elements; supplement it with clear labels, icons, or underlines to provide alternative cues. Consider offering a high-contrast mode option for your website or application, allowing users to customize the color scheme to their preferences and improve overall accessibility.
