General Information about Ultramarine (#08009B)

The color #08009B, commonly known as Ultramarine, is a deep, vibrant shade of blue. It belongs to the blue color family and is often associated with depth, stability, and trust. In the RGB color model, it is composed of 3.14% red, 0% green, and 61.18% blue. The name 'Ultramarine' originates from the Latin 'ultramarinus,' meaning 'beyond the sea,' as it was originally derived from the mineral lapis lazuli, imported from distant lands. Historically, Ultramarine was a highly valued pigment used in paintings, particularly during the Middle Ages and Renaissance. Its rarity and brilliance made it more expensive than gold, reserving its use for important figures and religious iconography. Today, synthetic versions of Ultramarine are widely available, making it accessible for various applications, including digital design, printing, and textiles.

The hex color #08009B, also known as Ultramarine, presents some accessibility challenges, particularly when used as a foreground color against a white or light background. Due to its low lightness value, the contrast ratio may fall below the WCAG (Web Content Accessibility Guidelines) recommended levels for text legibility. Specifically, for small text, a contrast ratio of at least 4.5:1 is recommended, and for large text (14pt bold or 18pt regular), a ratio of 3:1 is required. When using Ultramarine, it is crucial to ensure sufficient contrast. To improve accessibility, consider pairing it with lighter shades of yellow, white, or other high-contrast colors. Alternatively, using Ultramarine sparingly for decorative elements rather than essential text can mitigate accessibility issues. Testing with accessibility evaluation tools is recommended to verify compliance with WCAG standards. When used with other colors, consider their combinations, use a color combination tool to check the contrast of the color with black or white.
