General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1A0D91, is a deep and rich shade of blue. It belongs to the family of blue colors and is often associated with feelings of depth, stability, and sophistication. This particular shade of blue is created by combining a small amount of red and green with a significant amount of blue, which results in its distinctive dark and intense appearance. In color theory, Ultramarine is often used to evoke a sense of calmness and serenity, while also conveying a sense of authority and trustworthiness. The color's name comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious mineral lapis lazuli, imported from far-off lands. Ultramarine has been used for centuries in art and design.

The color #1A0D91, also known as Ultramarine, presents some accessibility challenges, particularly concerning contrast. When used as a background color, it requires very light text to ensure readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. Using a color contrast checker is essential to verify compliance. Consider avoiding using #1A0D91 for crucial textual information without careful pairing with an appropriate foreground color. Moreover, individuals with visual impairments might find it difficult to distinguish elements using this dark color if surrounding elements are not significantly brighter. Employing sufficient spacing and clear visual cues can help mitigate these issues. When using this color for interactive elements such as buttons or links, ensure that hover and focus states provide sufficient contrast change to indicate interactivity.
