Ultramarine

#0D118E

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0D118E, is a deep, rich blue pigment originally derived from the precious mineral lapis lazuli. Its name literally means "beyond the sea" because it was imported to Europe from Asia by sea during the Middle Ages and Renaissance. Because of its origin, it was an expensive pigment, used by the Renaissance painters for only the most important figures in their paintings, especially for the robes of the Virgin Mary. The synthetic version of ultramarine is much more affordable today and is widely used in various applications, including paints, plastics, and cosmetics. Its unique hue results from the presence of polysulfide ions within the aluminosilicate lattice structure.

The color #0D118E, a deep shade of ultramarine, presents certain accessibility challenges, especially when used as a text color. Due to its low luminance value, it offers insufficient contrast against light backgrounds, potentially making it difficult for users with visual impairments to read. To ensure accessibility, it is crucial to pair #0D118E with a background color that provides a high contrast ratio, ideally exceeding the WCAG (Web Content Accessibility Guidelines) recommended contrast ratio of 4.5:1 for normal text and 3:1 for large text. Using lighter shades of yellow, white, or even light grays as background colors can significantly improve readability. Additionally, when using #0D118E for interactive elements like buttons or links, providing sufficient visual cues, such as underlines or borders, can enhance usability for all users, including those with color vision deficiencies.
