General Information about Ultramarine

Ultramarine, represented by the hex code #0D0DA7, is a deep, rich blue color with a strong historical significance. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it originally referred to the pigment made from lapis lazuli, a precious stone sourced from mines far beyond the European coastline. In the past, the process of extracting the pigment from the lapis lazuli was extremely labor-intensive, which made the pigment very expensive. Because of that, the color was often reserved for paintings of special importance, like the robes of the Virgin Mary in religious art. Today, ultramarine is synthetically produced, making it more affordable and accessible. It evokes feelings of serenity, depth, and sophistication, often associated with the sea and sky. In color psychology, blue represents trust, loyalty, wisdom, confidence, intelligence, faith, truth and heaven.

The hex color #0D0DA7, also known as Ultramarine, presents some accessibility challenges, especially concerning color contrast. When used as a background color, it necessitates very light text (white or near-white) to ensure readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine, being a dark shade, often falls short of these recommendations when paired with mid-tone grays or colors. Therefore, it's crucial to use contrast checking tools during design and development. Moreover, avoid using Ultramarine for essential interface elements or text where readability is paramount. For users with visual impairments, a lack of sufficient contrast can make it difficult or impossible to perceive the content. Thoughtful color choices improve usability for everyone, including those with color vision deficiencies or low vision.
