Ultramarine

#1B0893

General Information

Ultramarine, represented by the hexadecimal color code #1B0893, is a deep, vivid shade of blue. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it one of the most expensive and highly valued pigments. Its name literally means "beyond the sea," reflecting its origin from stones imported into Europe from distant lands. Today, synthetic ultramarine is widely available, offering the same rich color at a fraction of the cost. Ultramarine is known for its excellent lightfastness and stability, making it a reliable choice for various applications. The color is associated with depth, wisdom, and tranquility, often used to evoke a sense of calm and authority. In color psychology, dark blues like ultramarine can also represent trust and security.

The hex color #1B0893, also known as Ultramarine, presents some accessibility challenges, particularly in text applications. Its dark hue results in low contrast against lighter backgrounds, which can make it difficult for users with visual impairments to read. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text to meet WCAG (Web Content Accessibility Guidelines) standards. When using #1B0893 for text, it's crucial to pair it with a very light color, such as white or a pale yellow, to ensure sufficient contrast. For decorative elements, the contrast requirements are less stringent, but it's still important to consider the overall visual experience. Employing tools that check color contrast ratios can help designers make informed decisions to improve accessibility. In interactive elements, consider the color contrast for focus states too.
