General Information about Ultramarine (#0F098F)

Ultramarine, represented by the hexadecimal color code #0F098F, is a deep blue pigment originally derived from the precious stone lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported into Europe from Asia. Historically, it was one of the most expensive and highly prized pigments, used by Renaissance artists like Michelangelo and Raphael for their most important works. Chemically, it is a complex sodium aluminosilicate containing sulfur, giving it its distinctive color. Today, synthetic ultramarine is widely available, offering the same vibrant hue at a fraction of the cost. It remains a popular choice in various applications, from paints and inks to cosmetics and plastics, prized for its stability and lightfastness.

The color #0F098F, also known as Ultramarine, presents significant accessibility challenges due to its dark hue. When used as a background color, it necessitates very light text to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines), the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Ultramarine's darkness means that only colors like white or very light yellow will likely meet these contrast requirements. When used for interactive elements like buttons or links, consider providing clear visual cues beyond just color, such as underlines or borders, to assist users with visual impairments. Ensuring sufficient contrast is crucial for users with low vision or color blindness to perceive content effectively. Therefore, careful consideration and testing are essential when implementing this color in user interfaces to maintain inclusivity and usability.
