About Ultramarine

Ultramarine, represented by the hex code #070A91, is a deep blue color with a rich history. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from ground lapis lazuli, a rare and expensive stone imported from Afghanistan. This made ultramarine one of the most prized and costly pigments during the Middle Ages and Renaissance, often reserved for depicting the robes of the Virgin Mary in religious paintings. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a fraction of the cost. It's known for its stability and lightfastness, making it a popular choice in various applications, from art and design to textiles and cosmetics, carrying a legacy of artistic and cultural significance.

The color #070A91, a deep ultramarine, presents several accessibility considerations for web development. Due to its low luminance, it requires careful attention to contrast ratios, especially when used for text or interactive elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against the background. Using this color for text on a white or light background would likely fail these contrast tests, making it difficult for users with visual impairments to read. To improve accessibility, consider pairing #070A91 with a much lighter color for text or using it sparingly for decorative elements where contrast is less critical. Providing alternative high-contrast themes can also significantly enhance the user experience for those with visual sensitivities.
