Its dark hue results in low contrast when used as a foreground color on a white or light background, potentially making text difficult to read for users with visual impairments. To ensure readability, it is crucial to pair this color with a sufficiently light background color that provides a contrast ratio meeting WCAG guidelines (ideally 4.5:1 for normal text and 3:1 for large text). Furthermore, avoid using #0b1d2f as the sole means of conveying important information, such as in links or buttons, without additional cues like underlines or icons. Considering users with color blindness, verify that information remains understandable even when color is not discernible. Thoroughly test color combinations with accessibility evaluation tools to guarantee compliance with accessibility standards and provide an inclusive user experience.
