General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F158C, is a deep and intense shade of blue. It is often associated with royalty, wisdom, and spirituality. This color derives its name from the pigment originally made from lapis lazuli, a semi-precious stone mined in Afghanistan. During the Middle Ages and Renaissance, Ultramarine pigment was highly prized and expensive, making it a color reserved for important works of art and religious iconography, especially for depicting the robes of the Virgin Mary. Modern Ultramarine is a synthetic pigment, making it more accessible and widely used in various applications, from paints and dyes to plastics and cosmetics. Its rich and saturated hue evokes feelings of depth, tranquility, and authority.

The color #0F158C, a deep shade of blue often referred to as Ultramarine, presents specific accessibility challenges, particularly in web design. Due to its low lightness value, it has inherently poor contrast with lighter text or background colors. According to WCAG guidelines, sufficient contrast is crucial for readability, especially for users with visual impairments. To ensure accessibility, pairing #0F158C with very light colors, such as white (#FFFFFF) or light yellow (#FFFFE0), is recommended. Tools like contrast checkers can verify compliance with accessibility standards. When used as a background, text should be substantially lighter. Avoid using this color for small text or crucial interactive elements unless accompanied by a high-contrast alternative. Thoughtful application is essential for inclusive design.
