Its hexadecimal code identifies its precise formulation within digital color systems, enabling consistent rendering across various media.

The color #18068D, a deep ultramarine, presents some accessibility challenges, particularly regarding color contrast. When used as a background color, it necessitates very light text (ideally white or a near-white shade) to ensure sufficient contrast for readability, meeting WCAG guidelines for contrast ratios. Conversely, using this color for text requires a very light background. Avoid pairing it with mid-tone colors, as the contrast will likely be insufficient for users with visual impairments. When using this color for interactive elements such as buttons or links, consider providing additional visual cues besides color alone, such as underlines, borders, or icons, to ensure usability for colorblind users. Thoughtful consideration of text size and font weight can also improve legibility against this dark background.
