General Information about Ultramarine

Ultramarine, represented by the hex code #180299, is a deep, vivid blue color. Its name originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the precious gemstone lapis lazuli, imported from faraway lands. Historically, Ultramarine was highly valued and expensive, reserved for use in important works of art, particularly in religious paintings to depict the robes of the Virgin Mary. Today, synthetic Ultramarine is readily available, making it more accessible for various applications. This color is often associated with royalty, wisdom, and spirituality due to its historical significance and rich hue. In color psychology, it can evoke feelings of tranquility, stability, and trust. The color's intensity and depth create a sense of sophistication and elegance, making it a popular choice in diverse industries.

The hex color #180299, also known as Ultramarine, presents significant accessibility challenges, especially in web design. Its very dark hue results in extremely low contrast against typical light backgrounds, such as white or light gray. This low contrast makes it difficult for users with visual impairments, including those with low vision, color blindness, or age-related macular degeneration, to read text or distinguish important interface elements. Ensuring sufficient contrast is crucial for WCAG compliance (Web Content Accessibility Guidelines). A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Using #180299 with light text is unlikely to meet these standards. Careful consideration should be given to pairing this color with a much lighter color to achieve acceptable contrast levels, or alternative, more accessible color choices should be explored to guarantee an inclusive user experience.
