General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1f10a4, is a deep, vivid blue hue with a rich history and widespread use. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' the name reflects its historical origin as a pigment sourced from the mineral lapis lazuli, imported to Europe from faraway lands like Afghanistan. In art, Ultramarine has long been prized for its exceptional brilliance and permanence, often reserved for depicting figures of great importance, such as the Virgin Mary. Its chemical composition involves a complex sodium aluminosilicate with sulfur, contributing to its characteristic color. Today, synthetic versions of Ultramarine are readily available, making it more accessible and affordable for various applications. It is a color with a rich historical and cultural background.

The color #1f10a4, also known as Ultramarine, presents some accessibility challenges, especially when used as a foreground color against a white or light background. Due to its dark hue and low luminance, the contrast ratio might fall below the WCAG (Web Content Accessibility Guidelines) recommended levels for text readability. Specifically, for small text, a contrast ratio of at least 4.5:1 is advised, and for large text, a ratio of 3:1 is recommended. Therefore, when using #1f10a4 for text, it is crucial to pair it with a sufficiently light background to ensure readability for users with visual impairments. If contrast requirements are not met, users with low vision may struggle to distinguish the text from the background. Similarly, individuals with color vision deficiencies may have difficulty perceiving the text clearly. A possible solution involves adjusting the color to a slightly lighter shade or using a brighter background color to achieve the required contrast ratio, thus enhancing accessibility. Always test color combinations using accessibility evaluation tools to ensure compliance with WCAG standards.
