General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #0A11AA, is a deep, vivid shade of blue. It derives its name from the Latin 'ultramarinus', meaning 'beyond the sea,' as the original pigment was made from lapis lazuli imported from Asia. Historically, Ultramarine was highly prized and expensive, making it a color reserved for royalty and religious figures in paintings. Today, synthetic versions of Ultramarine are widely available, making it accessible for various applications. In color theory, Ultramarine is considered a primary color, forming a foundation for mixing other hues. Its intense saturation and cool undertones evoke feelings of calmness, stability, and sophistication. The color is often associated with trust, intelligence, and authority, making it a popular choice for corporate branding and government institutions. In art and design, Ultramarine can be used to create depth and dimension, or to add a touch of elegance and drama to a composition.

The color #0A11AA, also known as Ultramarine, presents some accessibility challenges, particularly in text-based applications. Its low lightness value means that it requires careful consideration of contrast ratios against background colors. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive content effectively. When using Ultramarine for text, it is crucial to pair it with a light background to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. This ensures readability for individuals with moderate visual impairments. Conversely, using Ultramarine as a background color requires light-colored text to meet accessibility standards. Designers should use contrast checking tools to verify compliance with WCAG guidelines and consider providing alternative color schemes to accommodate users with different visual preferences or needs. Additionally, avoid using Ultramarine as the sole means of conveying important information, as colorblind users may not be able to distinguish it from other colors. Supplement color cues with text labels or icons to ensure that information is accessible to all users.
