Ultramarine
General Information about Ultramarine
Ultramarine, represented by the hex code #0B1591, is a deep, rich blue color. It is named after the pigment derived from lapis lazuli, a semi-precious stone, which was historically ground and processed to create the vibrant blue hue used by artists. Because of the laborious process, the pigment was incredibly expensive, making it a color reserved for painting important figures such as Jesus or the Virgin Mary. In modern times, ultramarine is synthetically produced, making it readily available for various applications. In the RGB color model, #0B1591 consists of 4.3% red, 8.2% green, and 56.9% blue. It falls within the blue color family and conveys feelings of stability, trust, and authority. The color is often associated with royalty, intelligence, and the ocean.
The color #0B1591, a deep ultramarine, presents significant accessibility challenges. Its extremely low lightness value of approximately 4% means it offers very poor contrast against white text or backgrounds. This fails WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and even large text (AA). Using this color for text or important UI elements against a light background would make content extremely difficult, if not impossible, for many users to read, especially those with visual impairments. To improve accessibility, pair it with very light colors like white (#FFFFFF) or very light grays, but always check contrast ratios. Consider using this color sparingly for decorative elements where legibility is not critical, or use a different color altogether.

Applications
Web Design
In web design, ultramarine can serve as a sophisticated accent color, adding depth and richness to a site's palette. It's particularly well-suited for backgrounds in headers or footers, or as a highlight color for key interactive elements. However, due to its darkness, it's crucial to pair it with light text to ensure readability and meet accessibility standards. Ultramarine can evoke feelings of trust and reliability, making it a good choice for professional or corporate websites.
Interior Design
In interior design, ultramarine can be used to create a luxurious and calming atmosphere. Consider using it as an accent wall in a bedroom or study, or incorporating it through textiles like curtains or cushions. It pairs well with neutral colors like white, gray, and beige, as well as metallic accents like gold or silver. Ultramarine can also be used in smaller doses, such as in artwork or decorative objects, to add a pop of color to a room.
Fashion
In fashion, ultramarine can be used to create striking and elegant outfits. A dress or suit in this color can make a bold statement, while accessories like scarves or handbags can add a touch of sophistication to a more neutral ensemble. It works well with both warm and cool colors, and can be dressed up or down depending on the occasion. Ultramarine is a versatile color that can be worn year-round.
