Ultramarine
General Information about #0B11A9
The color #0B11A9, also known as Ultramarine, is a deep, vivid blue that evokes feelings of sophistication, depth, and authority. It is located in the blue region of the color spectrum and is characterized by its high saturation and relatively low brightness. Historically, ultramarine was derived from the precious gemstone lapis lazuli, making it a highly prized pigment, particularly in Renaissance paintings. Today, it is synthetically produced, making it more accessible while retaining its rich and intense hue. In color psychology, Ultramarine is often associated with trustworthiness, intelligence, and loyalty, which makes it a popular choice for branding in industries that wish to convey these qualities. The hexadecimal color code #0B11A9 consists of 4.39% red, 6.67% green and 66.27% blue.
The color #0B11A9, a deep ultramarine, presents significant accessibility challenges. Its very low lightness value (close to black) means that it requires very light text to provide sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using #0B11A9 for text on a white background would fail these requirements. Therefore, if this color is used for text, it must be paired with colors like white (#FFFFFF) or very light shades of gray to ensure readability, especially for users with visual impairments. Similarly, if it is used as a background, text must be carefully chosen to meet contrast standards. Using color contrast tools can help in determining the right text/background color combinations to achieve WCAG compliance and inclusive design.
