General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #110D8A, is a deep blue pigment originally derived from the gemstone lapis lazuli. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was imported to Europe from mines in Asia. Historically, it was highly prized and expensive, often reserved for important religious paintings and the robes of the Virgin Mary. Today, synthetic ultramarine is widely available, making it an accessible color for various applications. In the RGB color model, #110D8A is composed of 6.67% red, 5.1% green, and 54.12% blue. It is characterized by its strong blue hue and relatively low saturation, giving it a rich and intense appearance. This color evokes feelings of depth, stability, and sophistication.

The color #110D8A, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its dark hue and low luminance, it is essential to ensure sufficient contrast when using it as a background or foreground color. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Pairing Ultramarine with lighter colors, such as whites, yellows, or light blues, can help meet these contrast requirements. Additionally, consider providing alternative text descriptions for images or icons using this color, ensuring that users with visual impairments can still understand the content. Avoid using Ultramarine for critical interactive elements without proper contrast, as this can hinder usability for all users, especially those with low vision or color blindness. Thoroughly testing your designs with accessibility tools and user feedback can help identify and address any potential issues.
