Ultramarine

#0B0992

General Information about Ultramarine

Ultramarine, represented by the hex code #0B0992, is a deep, vivid blue color that historically derives its name from the pigment made from lapis lazuli stone. This pigment was highly prized in the Middle Ages and Renaissance, making ultramarine one of the most expensive and revered colors used by artists. Today, ultramarine is synthetically produced, making it more accessible. In color theory, ultramarine is considered a cool color, evoking feelings of calmness, depth, and stability. It is often associated with royalty, wisdom, and spirituality. Due to its richness and intensity, ultramarine is often used to create a sense of drama or importance in visual designs.

The color #0B0992, a deep ultramarine, presents some accessibility challenges, especially for users with visual impairments. Its low luminance of just 2% means that text rendered in this color requires careful consideration of contrast ratios. According to WCAG guidelines, normal text should have a contrast ratio of at least 4.5:1 against its background, while large text (14pt bold or 18pt regular) needs a minimum ratio of 3:1. Using #0B0992 for text on a white background will not meet these requirements. To improve accessibility, pair it with much lighter colors like white, yellow, or pale blues for text or interactive elements. Avoid using it for critical information or calls to action without ensuring sufficient contrast. Furthermore, consider providing alternative visual cues or text descriptions for users who might have difficulty distinguishing this color.
