About Ultramarine

Ultramarine, represented by the hexadecimal color code #0B1090, is a deep, intense shade of blue. It derives its name from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from Asia. Historically, it was made from ground lapis lazuli, making it a highly prized and expensive pigment, often reserved for important figures and religious art. In modern times, Ultramarine is synthetically produced, making it more accessible for various applications. This color evokes feelings of calmness, trust, and authority. In color psychology, blue is often associated with stability, wisdom, and confidence. Because of its depth, #0B1090 can add sophistication and elegance to design projects.

The hex color #0B1090, also known as Ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a background color, it requires very light text (ideally white or near-white) to ensure sufficient contrast for readability, meeting WCAG (Web Content Accessibility Guidelines) standards. A contrast ratio of at least 4.5:1 for normal text and 3:1 for large text is recommended. Using this dark blue as a text color should be avoided on darker backgrounds, as the already low contrast will make it difficult to read. Tools like WebAIM's contrast checker can be invaluable in assessing the contrast ratio. Ensure that interactive elements using this color have clear visual cues beyond color alone to assist users with visual impairments. Furthermore, providing alternative styling options can enhance accessibility for a broader audience. Remember to test your designs with real users, including those with visual impairments, to validate accessibility.
