About Ultramarine

Ultramarine, represented by the hexadecimal color code #0B098F, is a deep and intense shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly prized pigments. Its name literally means 'beyond the sea,' referencing its origin from lands east of the Mediterranean. In modern times, synthetic ultramarine is readily available, offering the same rich color at a fraction of the cost. This color evokes feelings of depth, intelligence, and tranquility. It is often associated with royalty, wisdom, and the vastness of the ocean and night sky. Its unique depth makes it suitable for a variety of applications.

The color #0B098F, a deep ultramarine, presents accessibility challenges, particularly concerning color contrast. When used as a foreground color, it requires a light background to ensure sufficient contrast for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text, as per WCAG guidelines. This color should be avoided for critical interactive elements like buttons or links if a sufficiently contrasting color cannot be guaranteed. Careful consideration should be given to users with color vision deficiencies who might struggle to distinguish this dark blue from other dark shades. Testing with accessibility tools is essential to validate color pairings.
