General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0F009B, is a deep blue hue with a rich history. Derived from the Latin 'ultramarinus,' meaning 'beyond the sea,' it was originally made from ground lapis lazuli, a rare and expensive gemstone imported from Afghanistan. This explains its historical association with royalty and religious art, where it was highly prized for its vivid and lasting color. Today, synthetic ultramarine is widely available, offering the same vibrant color at a much lower cost. In the RGB color model, #0F009B is composed of 5.9% red, 0% green, and 61.2% blue. It is frequently used in graphic design, web development, and various artistic applications to convey feelings of trust, stability, and sophistication. Its distinctive depth sets it apart from lighter shades of blue, making it a powerful tool for visual communication.

The hex color #0f009b, also known as Ultramarine, presents several accessibility challenges for web developers. Its dark hue results in low contrast against lighter backgrounds, potentially making text and interactive elements difficult to read for users with visual impairments. According to WCAG guidelines, sufficient contrast ratios are crucial for ensuring readability. To improve accessibility, consider pairing #0f009b with very light colors, such as white or light yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Additionally, avoid using this color for essential visual cues without providing alternative indicators, such as labels or icons, to accommodate users who may not perceive color differences effectively. Thorough testing with accessibility tools is recommended to validate the design's compliance with accessibility standards.
