General Information about Ultramarine

Ultramarine, represented by the hex code #130D8B, is a deep blue pigment originally derived from the mineral lapis lazuli. Its name comes from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was imported into Europe from Asia. Historically, it was a highly prized and expensive pigment, often reserved for important figures in paintings, such as the Virgin Mary. In modern times, synthetic ultramarine is widely available, making it an accessible and versatile color for various applications, ranging from artistic endeavors to commercial design projects. It provides a sense of stability and professionalism, making it very popular.

The color #130D8B, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as text, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios. Insufficient contrast can make content difficult to read, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using tools like a contrast checker is crucial to ensure readability. For interactive elements like buttons, sufficient contrast is equally important. Avoid using this color for crucial information without ensuring proper contrast. Consider using it sparingly as an accent color, or pair it with lighter shades to improve overall accessibility and user experience. Testing with various user groups and assistive technologies can further refine color choices.
