General Information about Ultramarine

Ultramarine, represented by the hex code #000098, is a deep, rich shade of blue. Its name originates from the Latin "ultramarinus," meaning "beyond the sea," as it was originally derived from the precious mineral lapis lazuli, which was imported to Europe from distant lands. Chemically, ultramarine is a complex sodium aluminum silicate with sulfur, giving it its distinctive hue. Historically, ultramarine pigment was highly valued and expensive, often reserved for important artistic commissions, such as depicting the robes of the Virgin Mary in religious paintings. Modern synthetic ultramarine is more affordable and widely used in paints, cosmetics, and plastics. The color is associated with depth, stability, and sophistication, and is often used to evoke feelings of tranquility and trust.

The hex color #000098, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based contexts. Its very low luminance of approximately 0.0007 makes it difficult to achieve sufficient contrast against lighter backgrounds, including the standard white (#FFFFFF). According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. Ultramarine often fails to meet these criteria, especially for smaller text sizes. To enhance accessibility, consider using Ultramarine sparingly, primarily for decorative elements or backgrounds where text is not overlaid. If text is necessary, pair it with a very light color, such as white or a pale yellow, and meticulously test the contrast ratio using online tools to confirm compliance with accessibility standards. Alternative, brighter shades of blue or other colors might be more suitable for text elements in many user interfaces.
