General Information about Ultramarine (#0D0F8A)

The hexadecimal color #0D0F8A, also known as Ultramarine, is a deep shade of blue. It is composed of 5.1% red, 5.9% green, and 54.1% blue. In the RGB color model, this translates to 13 red, 15 green, and 138 blue. Ultramarine is often associated with feelings of calmness, serenity, and stability, making it a popular choice in various design applications. The color's depth and richness can evoke a sense of sophistication and elegance. In color psychology, blue is often linked to trust, loyalty, and wisdom, making it suitable for corporate branding and designs aiming to convey professionalism and reliability. However, its darkness requires careful consideration of contrast and accessibility to ensure readability and usability.

The color #0D0F8A, a deep ultramarine, presents several accessibility considerations. Its low luminance value (very dark) means it requires careful pairing with text or other foreground elements to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. When used as a background, bright text colors like white or light yellow are necessary to meet these guidelines. Conversely, if #0D0F8A is used for text, a very light background is essential. Additionally, avoid using this color to convey critical information without accompanying text or other visual cues, as users with color vision deficiencies may struggle to distinguish it from similar dark hues. Consideration should also be given to users with cognitive disabilities; clear visual hierarchy and simple layouts can help improve comprehension when using such a deep color.
