General Information about Ultramarine

Ultramarine, represented by the hex code #050693, is a deep, vivid blue color that historically derives from the pigment made of ground lapis lazuli stone. This pigment was highly valued and expensive, often used in medieval and Renaissance paintings to depict the robes of the Virgin Mary, signifying its preciousness. Nowadays, synthetic ultramarine is readily available, making the color more accessible for various applications. In the RGB color model, #050693 consists of 2% red, 2.4% green, and 57.6% blue. In the CMYK color model, it comprises 97% cyan, 97% magenta, 0% yellow, and 42% black. Ultramarine is often associated with feelings of calmness, depth, and sophistication, making it a popular choice in design and art.

The hex color #050693, also known as Ultramarine, presents considerable accessibility challenges, particularly in web design. Its dark hue results in very low contrast when paired with lighter text or background elements. According to WCAG (Web Content Accessibility Guidelines), sufficient contrast between foreground and background colors is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine falls significantly short of these guidelines when combined with common lighter colors like white or light gray. To improve accessibility, consider using a much lighter color for text or interactive elements against an Ultramarine background, or alternatively, using Ultramarine as an accent color sparingly, ensuring it's not essential for conveying information. Tools like contrast checkers can help verify compliance with accessibility standards.
