General Information

The hexadecimal color code #0D0D89 represents a dark shade of blue, specifically known as Ultramarine. In the RGB color model, it consists of 5.1% red, 5.1% green, and 53.7% blue. This color is often associated with depth, stability, and sophistication. Its low lightness value makes it unsuitable for text on a white background without careful consideration of contrast. Historically, ultramarine was derived from the mineral lapis lazuli, making it a highly prized and expensive pigment. Today, synthetic versions allow for broader use in various applications. In color psychology, dark blue is often linked to trustworthiness and reliability. It is used in corporate branding to convey professionalism and security. Its rich and intense hue makes it a favorite for artistic and design purposes.

The color #0D0D89, a deep ultramarine, presents several accessibility considerations for web developers. Its low lightness value means it requires careful pairing with contrasting colors to ensure readability. When used for text, it's crucial to choose a light background color to meet WCAG (Web Content Accessibility Guidelines) standards for contrast ratio. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. In terms of UI elements, using this color for interactive components requires clear visual cues beyond just color, such as labels or icons, to assist users with visual impairments. Also, avoid using it as the sole indicator for conveying information, as color blindness affects a significant portion of the population. Consider providing alternative cues like text labels or shapes to enhance usability for all users. Testing the color scheme with accessibility tools can help identify potential issues and ensure compliance with accessibility standards.
