Ultramarine

#0B009B

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0B009B, is a deep blue pigment originally derived from the precious stone lapis lazuli. Its name literally means "beyond the sea," referring to its importation into Europe from mines in Asia. Highly prized by Renaissance artists, ultramarine was more expensive than gold, often reserved for depicting the robes of the Virgin Mary. Today, synthetic ultramarine is widely available, offering the same rich hue at a fraction of the cost. This color evokes feelings of depth, stability, and wisdom. Its usage in design and art often signifies sophistication and trust. The color’s presence spans various applications, from fine art to modern graphic design, retaining its aura of luxury and refinement.

The color #0B009B, a deep ultramarine, presents significant accessibility challenges, especially in text applications. Its low luminance value results in poor contrast against light backgrounds, making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, it's essential to pair this color with a very light background, such as white or a pale yellow. Alternatively, using it sparingly for decorative elements rather than essential text can minimize accessibility issues. When used for interactive elements, ensure proper focus indicators are in place. Careful consideration and testing with accessibility tools are necessary to avoid creating barriers for users.
