General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1C0B90, is a deep, rich blue color reminiscent of the pigment derived from lapis lazuli. Historically, ultramarine was one of the most expensive and prized pigments, used by Renaissance painters to depict the robes of the Virgin Mary and other important figures. The name "ultramarine" comes from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported to Europe from mines in Afghanistan. Today, synthetic ultramarine is widely available, making it a more accessible color for various applications. In color theory, ultramarine is considered a cool color, often associated with feelings of calmness, serenity, and wisdom. Its depth and intensity make it a popular choice for creating a sense of sophistication and elegance.

The hex color #1C0B90, a deep ultramarine, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value, indicative of its darkness, results in poor contrast against lighter backgrounds. This is critical in web design, where sufficient contrast between text and background is essential for readability. According to WCAG guidelines, the contrast ratio should be at least 4.5:1 for normal text and 3:1 for large text. Using #1C0B90 as a background color for light text would likely fail these criteria, making it difficult for users with low vision or color blindness to perceive the content. Therefore, it is crucial to pair this color with very light shades or consider alternative, more accessible color combinations to ensure inclusivity and usability for all users. Tools like contrast checkers can help evaluate the contrast ratio and determine if a color combination meets accessibility standards.
