General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0A0891, is a deep, vivid blue pigment that has been prized for centuries. Derived originally from the precious stone lapis lazuli, its name literally means "beyond the sea," reflecting its origin from stones imported into Europe from far-off lands. In art history, Ultramarine was highly valued by Renaissance painters for its brilliance and permanence, often reserved for depicting the robes of the Virgin Mary due to its cost and prestige. Today, synthetic versions of Ultramarine are widely available, making it accessible for various applications. It belongs to the blue color family, known for its associations with calmness, stability, and wisdom. Its strong saturation makes it a visually impactful color, and its historical significance adds a layer of richness and depth.

The color #0A0891, a deep, saturated blue, presents several accessibility considerations for web developers. Its low luminance (darkness) means it requires careful pairing with contrasting colors to ensure readability. When used as a background, white or very light colors are necessary for text to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratios (minimum 4.5:1 for normal text and 3:1 for large text). Avoid using this color for critical interactive elements without sufficient contrast, as users with visual impairments may struggle to discern them. Moreover, consider users with color vision deficiencies; while this blue is distinct, ensure sufficient contrast with adjacent colors to prevent blending or misinterpretation. Providing alternative text descriptions for images using this color is also beneficial. Thoughtful application of #0A0891, considering its impact on users with varying abilities, is essential for inclusive design.
