General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0C0497, is a deep blue pigment originally derived from the precious mineral lapis lazuli. Its name literally means 'beyond the sea,' reflecting its import from overseas sources in ancient times. Chemically, modern Ultramarine is a complex sodium aluminosilicate containing sulfur. It exhibits a rich, intense color due to the presence of polysulfide ions within its crystal structure. Ultramarine is highly valued for its lightfastness, stability, and non-toxicity, making it a popular choice in various applications, from fine art to industrial coatings. Its unique hue and historical significance contribute to its enduring appeal across diverse cultures and artistic traditions.

The color #0C0497, also known as Ultramarine, presents several accessibility considerations for web developers. Due to its deep, dark hue, it's crucial to ensure sufficient contrast when using it for text or interactive elements. 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 light colors like white, light yellow, or light gray can help meet these requirements. Avoid using it with other dark colors, as this would render content illegible for users with visual impairments. When using Ultramarine as a background color, ensure that all interactive elements have clear visual cues to indicate their function, such as borders or hover effects. Employing accessibility testing tools can also help identify and rectify any potential contrast issues, fostering a more inclusive user experience.
