General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #090098, is a deep and intense shade of blue. It is a dark color, bordering on the edge of being perceived as black in certain lighting conditions. Historically, the term 'ultramarine' refers to a pigment originally made from ground lapis lazuli, a rare and expensive stone. This pigment was highly prized by Renaissance painters for its vibrant and long-lasting color. The chemical composition of ultramarine is a complex sodium aluminosilicate with sulfur, giving it its distinct hue. Today, synthetic ultramarine is widely available, offering a more affordable alternative to the natural pigment. In color theory, ultramarine is associated with depth, stability, and wisdom. It often evokes feelings of tranquility, contemplation, and authority. Its darkness makes it more suitable for backgrounds or accents rather than primary text color.

The hex color #090098, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its extremely dark hue results in very low contrast against standard light backgrounds, such as white (#FFFFFF). This low contrast makes it difficult for users with visual impairments, including those with low vision or color blindness, to discern text or other visual elements rendered in this color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine falls far short of these recommendations when paired with typical background colors. Therefore, it is crucial to carefully consider the background color when using #090098. Pairing it with very light shades or using it sparingly for decorative elements rather than essential information is advised. To ensure accessibility, developers should use contrast checking tools to verify that the color combination meets the minimum contrast requirements. Alternative, lighter shades should be considered for text to improve readability and inclusivity.
