About Ultramarine

Ultramarine, represented by the hexadecimal color code #110A8E, 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 mines in Asia. Historically, it was one of the most expensive and highly prized pigments, often reserved for important artistic commissions, such as depictions of the Virgin Mary. Chemically, modern Ultramarine is a complex sodium aluminosilicate with sulfur. It is known for its intense color, lightfastness, and stability, making it a valuable pigment in various applications. Today, synthetic Ultramarine is widely available and used in paints, plastics, cosmetics, and other materials. It is still prized for its rich blue hue and its ability to create depth and dimension in artistic and design projects.

The color #110A8E, also known as Ultramarine, presents significant accessibility challenges, particularly in text applications. Its dark hue results in low contrast against lighter backgrounds, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. For text, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine may fail to meet these standards when paired with common background colors like white or light gray. To improve accessibility, consider using Ultramarine sparingly for decorative elements or pairing it with a much lighter color for text, ensuring the contrast ratio meets accessibility requirements. Tools are available online to check contrast ratios and assess the accessibility of color combinations. Providing alternative high-contrast themes also enhances usability for all users.
