Ultramarine

#0B0692

General Information about Ultramarine

Ultramarine, represented by the hex code #0B0692, is a deep blue color with a rich history. The name 'ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as the pigment was originally imported from mines in Afghanistan by sea. Historically, it was made by grinding lapis lazuli into a powder. Because lapis lazuli was a rare and expensive mineral, ultramarine was a pigment reserved for the most important commissions. Today, synthetic ultramarine is widely available, offering a more affordable alternative while retaining the same beautiful hue. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, trust, and authority. It's often associated with royalty, spirituality, and intelligence.

The color #0B0692, a deep ultramarine, presents significant accessibility challenges, especially in web design. Its low luminance value (relative to white) means that text rendered in this color on a white background may fail to meet the contrast ratios recommended by WCAG (Web Content Accessibility Guidelines). This can make content difficult to read for users with visual impairments, including those with low vision or color blindness. To ensure accessibility, it's crucial to pair this color with a very light color for text or interactive elements. A light shade of yellow or even a very pale gray could provide sufficient contrast. Developers should always use contrast checking tools to verify that their color choices meet accessibility standards. Also be mindful of using the color in images as users need to be able to distinguish elements of the image properly.
