Due to its relatively dark nature, it necessitates a light-colored background to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. This can be verified using online contrast checkers. Avoid pairing #104B8B with other dark colors, as this would render text difficult to read for users with visual impairments.

When used for interactive elements like buttons or links, ensure adequate visual cues beyond color alone, such as underlines or icons, to make these elements accessible to colorblind users.
