About Ultramarine

Ultramarine, represented by the hex code #020399, is a deep blue pigment historically derived from the gemstone lapis lazuli. Its name literally means "beyond the sea," reflecting its origin as a pigment imported from overseas during the Middle Ages and Renaissance. This rich, intense blue has been highly valued by artists for centuries due to its vibrant hue and permanence. Chemically, modern ultramarine is a complex sodium alumino-silicate with sulfur, closely resembling the natural mineral lazurite. It's known for its resistance to fading and its stability under various conditions. Its distinct color arises from the presence of polysulfide radicals within its crystal lattice. Today, synthetic ultramarine is widely available and used in paints, cosmetics, plastics, and other applications where a strong, stable blue color is required.

The color #020399, a deep ultramarine, presents several accessibility challenges. Its extremely low luminance value makes it difficult to perceive, especially for users with low vision or color blindness. When used as a foreground color, it requires a very light background to meet WCAG (Web Content Accessibility Guidelines) contrast requirements. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ensure sufficient contrast by testing color combinations with accessibility tools. Avoid using this color for essential information or interactive elements without careful consideration of its impact on users with disabilities. Providing alternative text, using high-contrast icons, and offering customizable color schemes can help mitigate these accessibility concerns and create a more inclusive user experience. Remember to test your designs with assistive technologies to validate their accessibility.
