Ultramarine

#131088

General Information

Ultramarine, represented by the hexadecimal color code #131088, is a deep blue hue with a rich and historical background. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' the name reflects its original source – the precious mineral lapis lazuli, imported to Europe from mines in Afghanistan. Historically, ultramarine was highly valued and expensive, often reserved for use in religious art, particularly in paintings of the Virgin Mary. Its intense and vibrant color made it a symbol of holiness and purity. In modern times, synthetic ultramarine is widely available, making it accessible for various applications, including paints, plastics, and cosmetics. The color evokes feelings of depth, stability, and sophistication, making it a popular choice in design and branding.

The color #131088, also known as Ultramarine, presents several accessibility considerations for web design. Due to its dark hue, sufficient contrast is crucial when used as text or a background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text against its background. Lighter text colors, such as white or pale yellow, would enhance readability. Furthermore, avoid relying solely on color to convey important information; supplement color with text labels or icons to ensure accessibility for users with visual impairments. When using this color for interactive elements, ensure a clear visual focus indicator is present to aid keyboard navigation. Proper implementation enhances usability for all users, including those with disabilities. Testing with accessibility tools is recommended.
