#050B93

General Information about Ultramarine

Ultramarine, represented by the hexadecimal color code #050B93, is a deep and intense shade of blue. It is derived from the pigment lapis lazuli, a semi-precious stone that has been used since antiquity. Historically, ultramarine was highly valued and even more expensive than gold due to the laborious process of extracting it from the stone. Today, synthetic ultramarine is readily available, making it an accessible color for various applications. It is often associated with royalty, depth, and stability, and its rich tone lends itself well to both digital and physical design projects. The color evokes feelings of calm, trust, and authority. Due to its dark nature, it works best with lighter colors or in areas where it is not dominant.

The hex color #050B93, also known as Ultramarine, presents significant accessibility challenges due to its dark nature. When used as a foreground color, it requires a very light background to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This color may struggle to meet these ratios with many background colors, potentially causing eye strain and making content inaccessible. When using this color, it's crucial to perform thorough contrast checks with the intended background and adjust accordingly. Consider providing alternative color schemes to enhance usability for all users, or avoid using it for text entirely.
