About Ultramarine

Ultramarine, represented by the hex code #071491, is a deep blue color historically derived from the precious stone lapis lazuli. This color is known for its rich, intense hue, which has made it a prized pigment in art and decoration for centuries. In the RGB color model, #071491 is composed of 2.75% red, 7.84% green, and 56.86% blue. Its prominence in art dates back to the Middle Ages, when it was used extensively in illuminated manuscripts and religious paintings. The term "ultramarine" literally means "beyond the sea," referring to its origin from stones imported into Europe from distant lands. Today, synthetic ultramarine is widely available, making it more accessible for various applications, while retaining the essence of its original allure.

The hex color #071491, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low contrast against typical light-colored backgrounds, such as white or light gray. This low contrast can make text and other visual elements difficult to read for users with visual impairments, including those with low vision or color blindness. According to WCAG guidelines, sufficient contrast is crucial for ensuring content is perceivable. To improve accessibility, it's highly recommended to pair #071491 with much lighter colors that offer a contrast ratio of at least 4.5:1 for standard text and 3:1 for large text. Using tools to check contrast ratios is essential during the design process. Also avoid using it for important visual elements where clarity is paramount. Provide alternative styling options for users who need them.
