General Information about Ultramarine (#160D8A)

The color #160D8A, commonly known as Ultramarine, is a deep and intense shade of blue. It belongs to the blue color family and is often associated with qualities such as depth, stability, and tranquility. In the RGB color model, it is composed of 8.63% red, 5.1% green, and 54.12% blue. The name "Ultramarine" originates from the Latin "ultramarinus," meaning "beyond the sea," as the pigment was originally imported from overseas, primarily from Afghanistan. Historically, Ultramarine was derived from the mineral Lapis Lazuli and was highly prized for its brilliance and permanence, making it one of the most expensive pigments available. It was favored by Renaissance painters for depicting the robes of the Virgin Mary. Today, synthetic versions of Ultramarine are widely available, making it more accessible and affordable.

The color #160D8A, a deep ultramarine, presents some accessibility challenges, particularly concerning color contrast. When used as a foreground color for text, it necessitates a very light background to ensure sufficient contrast for readability, adhering to WCAG guidelines. Using white or very pale yellow can provide acceptable contrast ratios. However, pairing it with darker shades or colors of similar luminosity will render the text illegible for many users, especially those with visual impairments. In user interface design, it's crucial to avoid using this color for essential interactive elements without appropriate visual cues and sufficient contrast. Consider providing alternative high-contrast themes to accommodate users with different visual needs. Furthermore, when using this color to convey information, always supplement it with text labels or icons, as relying solely on color can exclude users with color blindness.
