About Ultramarine

Ultramarine, represented by the hexadecimal color code #1113A3, is a deep, vivid blue pigment that has been prized since antiquity. Originally derived from the precious gemstone lapis lazuli, its name literally means 'beyond the sea,' reflecting its historical origins as an imported pigment. In modern times, synthetic ultramarine is produced, offering a more affordable and consistent alternative to the natural pigment. The color's unique hue results from the presence of sulfur-containing compounds within its crystal structure. Ultramarine is widely used in various applications, including fine art, cosmetics, and industrial coatings. Its rich and intense color adds depth and vibrancy to paintings, fabrics, and other materials. Because it’s considered non-toxic, it is also widely used in the cosmetic industry. Historically, ultramarine was more valuable than gold and only used for important commissions.

The color #1113A3, also known as Ultramarine, presents potential accessibility challenges, especially when used as text on a background that lacks sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text to ensure readability for users with visual impairments. When pairing Ultramarine with lighter shades, it's crucial to verify the contrast ratio using online tools or accessibility checkers to confirm compliance. If the contrast ratio is insufficient, consider using a lighter tint of Ultramarine or a different color altogether to improve readability. For interactive elements such as buttons or links, providing sufficient visual cues beyond color alone is also important. This can include using underlines, borders, or icons to help users easily identify and interact with the elements. Careful attention to contrast and the use of supplementary visual cues can significantly enhance the accessibility of designs incorporating Ultramarine.
