Its unique hue makes it a popular choice in branding, design, and creative projects seeking to convey these qualities. However, its dark nature requires careful consideration of contrast and accessibility.

The color #120B8D, a deep ultramarine, presents considerable accessibility challenges. Its low luminance value of approximately 2% means it offers very little contrast against white backgrounds. According to WCAG guidelines, this color fails all levels of contrast ratio requirements for normal text, large text, and user interface components. To improve accessibility, it's crucial to pair this color with much lighter hues. White or very light shades of yellow, cyan, or even light grey could provide sufficient contrast. When used as a background, ensure the text is a contrasting color like white or a very light shade. Avoid using this color for essential interactive elements without careful consideration of contrast. For users with visual impairments, the lack of contrast could make content completely illegible. Always use contrast checkers to verify adequate contrast ratios before deploying this color in web applications or interfaces. Moreover, consider providing high-contrast themes for users who need them.
