General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0B168D, is a deep, rich blue pigment originally derived from the mineral lapis lazuli. Its name comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as lapis lazuli was imported to Europe from Asia. Historically, ultramarine was highly prized, often more expensive than gold, and reserved for the most important commissions, such as the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is readily available, making it more accessible for various applications. This color is characterized by its strong, pure blue hue with a slight violet undertone. In color psychology, it is associated with feelings of calmness, authority, and intelligence. Its depth and intensity make it a versatile choice for design and art.

The color #0B168D, a deep ultramarine, presents some accessibility challenges, especially when used for text or interactive elements. Due to its low lightness value, it requires careful consideration of contrast ratios. When using this color for text on a white or very light background, the contrast will likely be insufficient to meet WCAG (Web Content Accessibility Guidelines) standards for normal text (4.5:1) or large text (3:1). To ensure accessibility, it's crucial to pair this color with a very light color, such as white (#FFFFFF) or a light yellow (#FFFFE0), for text or interactive elements. Also, using #0B168D for background requires the use of very light colors for text or interactive elements. Consider the needs of users with visual impairments by verifying sufficient contrast with accessibility tools. Providing alternative visual cues, such as icons or borders, can further enhance usability for all users. Always test color combinations with assistive technologies to ensure a positive user experience.
