General Information about Ultramarine

Ultramarine, represented by the hex code #0B0A8E, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from Asia. Historically, ultramarine was highly prized and expensive, often used in Renaissance paintings to depict the robes of the Virgin Mary due to its symbolic association with holiness and purity. Today, synthetic ultramarine is widely available, making it more accessible for various applications. In color theory, ultramarine is considered a cool color, often associated with feelings of calmness, serenity, and authority. It is a versatile color used across different industries, ranging from art and design to fashion and marketing.

The color #0B0A8E, a deep ultramarine, presents several accessibility considerations for web design. Due to its low lightness value, it offers poor contrast when used as text against a white or light-colored background, potentially causing readability issues for users, especially those with visual impairments. To improve accessibility, it's crucial to pair this color with significantly lighter hues for text or interactive elements. Using a contrast checker tool is recommended to ensure WCAG compliance (Web Content Accessibility Guidelines), aiming for a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Also, avoid using this color as the sole indicator of functionality; supplement it with other cues like labels or icons to accommodate users with color blindness. Thoughtful application of this color can enhance the user experience for everyone.
