General Information about Ultramarine

Ultramarine, represented by the hex code #0D168B, is a deep blue color historically derived from the precious mineral lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported to Europe from Asia. This color is characterized by its rich, intense hue and has been prized for centuries in art and decoration. In modern color theory, Ultramarine is considered a cool color, often associated with depth, stability, and tranquility. It is commonly used in various applications, from fine art and graphic design to fashion and interior design, where its depth and elegance can add a touch of sophistication. Its popularity stems from its ability to evoke a sense of calm and its versatility in complementing a wide range of other colors.

The hex color #0D168B, also known as Ultramarine, presents several accessibility considerations for web design. Its dark hue results in a low contrast ratio when paired with similarly dark colors, potentially causing readability issues for users with visual impairments. According to WCAG guidelines, sufficient contrast between text and background colors is crucial for ensuring accessibility. Using #0D168B for text requires a light background color to meet minimum contrast requirements. When used for interactive elements like buttons or links, providing clear visual cues such as hover effects or underlines becomes important. Additionally, relying solely on color to convey information should be avoided; supplementary cues like text labels or icons enhance usability for colorblind users. Careful attention to these factors is vital to create inclusive and accessible web experiences.
