General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #2305AF, is a deep and intense blue hue reminiscent of the precious pigment derived from lapis lazuli. Its name, meaning 'beyond the sea,' reflects its historical origins, as lapis lazuli was imported to Europe from distant lands across the sea. This color carries a rich history, having been highly prized by artists throughout the ages for its vibrancy and permanence. In the RGB color model, Ultramarine is composed of 13.73% red, 1.96% green, and 68.63% blue. It possesses a sense of depth and mystery, often associated with qualities such as wisdom, trust, and stability. Ultramarine continues to be a popular choice in various creative fields, from painting and graphic design to fashion and interior design, adding a touch of elegance and sophistication to any project.

The color #2305AF, also known as Ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio against lighter backgrounds, making text and other elements difficult to read. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Ultramarine often falls short of these recommendations when paired with common background colors like white or light gray. Therefore, when using Ultramarine, it is essential to carefully select a foreground color that provides sufficient contrast. Lighter shades of yellow, white, or even brighter blues may offer better readability. Additionally, consider providing alternative visual cues, such as icons or patterns, to convey information and ensure accessibility for all users. Tools like contrast checkers can help evaluate color combinations and identify potential accessibility issues.
