#0B0098

General Information about Ultramarine

Ultramarine, represented by the hex code #0B0098, is a deep blue pigment originally derived from the precious gemstone lapis lazuli. Its name literally means "beyond the sea," reflecting its historical origins as a pigment imported into Europe from mines in Asia. Known for its rich, intense color and exceptional lightfastness, Ultramarine has been highly valued by artists since the Middle Ages. Due to its expense, it was often reserved for depicting important figures such as the Virgin Mary. In modern times, synthetic Ultramarine has become widely available, offering a more affordable alternative to the natural pigment. The chemical composition of synthetic Ultramarine is a complex sodium aluminosilicate containing sulfur, which gives it its characteristic blue hue. It is used in a variety of applications, including paints, plastics, and cosmetics.

The hex color #0B0098, also known as Ultramarine, presents some accessibility challenges, especially when used for text. Its dark hue results in a low contrast ratio against standard white backgrounds, potentially making it difficult for users with visual impairments to read. To improve accessibility, it's crucial to pair this color with lighter shades, such as white, light gray, or even pale yellow, to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #0B0098 for interactive elements like buttons or links, ensure a clear visual distinction upon hover or focus to aid users with cognitive disabilities. Thoroughly testing color combinations with accessibility evaluation tools is essential to create an inclusive design.
