General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #1C13A1, is a deep and vibrant shade of blue. It historically derives its name from the pigment originally made from lapis lazuli, a rare and precious stone sourced from beyond the sea ('ultra marinus' in Latin). This color is characterized by its strong blue hue with a slight hint of violet, contributing to its rich and intense appearance. In the RGB color model, #1C13A1 consists of 11% red, 7.5% green, and 63.1% blue. Its use in art dates back centuries, where it was highly valued for its brilliance and permanence. Today, Ultramarine continues to be a popular choice in various applications, including graphic design, web development, fashion, and interior decoration, valued for its association with depth, sophistication, and creativity. Its CMYK values are Cyan: 79%, Magenta: 88%, Yellow: 0%, Black: 37%.

The color #1C13A1, also known as Ultramarine, presents several accessibility considerations, particularly in web design. Due to its deep, saturated hue, it's crucial to ensure sufficient contrast when used as a background or text color. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet AA compliance. Ultramarine may not automatically meet these requirements when paired with lighter shades of gray or certain pastel colors. Using a color contrast checker is essential to verify compliance. Furthermore, avoid relying solely on color to convey important information, as users with color vision deficiencies may not be able to distinguish it. Supplement color cues with text labels, icons, or patterns to ensure inclusivity. For interactive elements like buttons or links, provide distinct visual cues such as changes in color or state on hover or focus to enhance usability for all users, including those with disabilities.
